Against the backdrop of increasingly strict global energy efficiency standards, permanent ferrite magnets are becoming the preferred magnetic material for energy conservation and consumption reduction in fields such as home appliances, automobiles, and industrial motors, thanks to their triple advantages of "low cost, high efficiency, and green manufacturing". 1. Material level: Performance improvement leads to direct energy conservation High residual magnetism + high coercive force The latest wet-pressed ferrite magnetic tiles have Br≥ 4.2kG and Hcj≥ 4.0kOe, which can output the same torque at a lower current. The copper loss and iron loss of the motor decrease by 8% to 15% simultaneously. Low-temperature sintering process The patented formula and secondary sintering at a low temperature of 1180 ℃ refine the grain structure, reduce eddy current loss, and further lower the energy consumption per ton of magnetic tiles by 5%.   2.Device level: Energy-saving of variable-frequency friendly amplification system Wide speed range and high efficiency The demagnetization inflection point of the high coercive force magnetic tile is flat, supporting the stable operation of DC inverter motors at a low frequency of 1 Hz, avoiding the waste of "a big horse pulling a small cart". The energy efficiency ratio of inverter air conditioners has thus increased by 20%. High-temperature stability The Curie temperature is 450 ℃, and the magnetic flux attenuation under the operating conditions of -30 ℃ to 120 ℃ is less than 3%, ensuring that the compressor and fan can still maintain high-efficiency zone operation under extreme weather conditions. Both volume and weight have decreased When the magnetic energy product is increased by 10%, the motor length can be shortened by 10% to 15%, directly reducing the usage of copper wires and silicon steel sheets, thus achieving "secondary energy conservation". 3.System Level: Waste Heat Utilization and Energy Conservation throughout the Entire Life Cycle Waste heat recovery of double-layer roller kiln The latest sintering kiln has led the 250 ℃ hot air from the cooling section back to the preheating and drying section, replacing electric heating. The daily production capacity of a single kiln is 20 tons, and the unit energy consumption has been reduced to 0.70 kWh/kg, saving 30% of electricity compared to traditional kilns. A super-long lifespan of 30 years Ferrite is corrosion-resistant and anti-oxidation, with a demagnetization rate of less than 3% for 30 years. It avoids the system efficiency decline caused by demagnetization or corrosion of rare earth magnets and does not require additional energy consumption compensation throughout its entire life cycle. From the perspective of the entire chain of "materials - devices - systems", permanent ferrite magnets, with their low raw material costs, low manufacturing energy consumption, low operating losses, and high reliable lifespan, provide scalable and replicable energy-saving solutions for the three major energy-consuming terminals of home appliances, automobiles, and industry. Driven by the "dual carbon" goals, ferrite permanent magnets are not only transitional substitutes but also long-term sustainable green magnetic cores.

When I turned on the smart door lock after work, the air conditioner had already started in advance. The refrigerator quietly keeps fruits and vegetables fresh. The sweeping robot shuttles through the living room. The car starts with a single button and the wipers move with the rain - behind these seemingly ordinary moments, there is an unremarkable small gray-black magnet: a permanent ferrite magnet. With its hard-core features of "affordable price, stable performance, high-temperature resistance and corrosion resistance", it has quietly integrated into every "functional chain" of modern life. I. Home Appliance Scenario: Making Comfort "Silent" Inverter air conditioning compressor The wet-pressed ferrite magnetic tiles form the motor rotor, and in combination with the frequency conversion algorithm, enable the air conditioner to operate smoothly at a low frequency of 1 Hz, saving 15% to 20% of electricity throughout the year. Refrigerator, washing machine, dishwasher The ferrite magnetic rings in the drainage pump, fan motor and detergent dispenser make it possible for the refrigerator to achieve low-noise cooling at 38 dB(A) and for the dishwasher to precisely dispensed detergent. Sweeping robot The virtual wall magnetic strips and wheel speed Hall magnetic rings achieve path planning and restricted area isolation, ensuring that the "lazy person's magic tool" does not cause any trouble. Ii. Automotive Scenario: The "Magnet Army" of a Single Vehicle Economy cars are equipped with over 20 small motors, while luxury cars have nearly 70. Start motor, electric seat, ABS, wiper, electric rearview mirror... Almost every motor has a ferrite tile. The global demand for ferrite permanent magnets for automobiles is expected to reach 450,000 tons in 2023, with a compound annual growth rate of 5% over five years. Against the backdrop of high oil prices and rare earth prices, ferrite continues to replace some rare earth permanent magnets with its "cost performance + temperature resistance". Iii. Consumer Electronics and Office Hard disk head positioning, notebook computer fans, laser printer paper feeding mechanisms, and electric toothbrush micro-motors - ferrite magnets provide "centimeter-level" precise movements with "millimeter-level" dimensions, ensuring the thinness and long battery life of the devices. Iv. Industry and Energy High-performance ferrite tiles are extensively used in photovoltaic inverters, energy storage converters, charging pile fans, and factory manipulator shaft drive motors to achieve the dual goals of "high energy efficiency and low cost". V. Future Outlook Process upgrade: Microwave sintering and nano-doping are increasing the magnetic energy product of ferrite by another 10%, further expanding its share in high-end motors. Green cycle: The ferrite raw materials are Fe₂O₃ and SrCO₃, which are abundant in source and do not require rare earths, in line with the sustainable route under the "dual carbon" background. From the grinding motor of the coffee machine in the early morning to the silent motor of the bedside fan at night, permanent ferrite magnets exist like air but are rarely seen. It is precisely this "unsung hero" who has made every "start", "speed regulation" and "silence" of modern life possible, and will continue to support the wave of electrification and intelligence of all things with lower costs and higher efficiency in the future.

When an inverter air conditioner starts to operate, the moment you press the remote control, the first thing to activate is not the fan visible to the naked eye, but the compressor motor hidden inside the outdoor unit. Permanent ferrite magnetic tiles are embedded in the rotor of this motor. They act like an "invisible commander", determining the cooling speed, energy consumption and noise level of the air conditioner. Compressor motor rotor Inverter air conditioners generally use DC brushless motors as the power source of the compressor, and the rotor is composed of multiple high-performance wet-pressed ferrite permanent magnet tiles spliced together. The fixed magnetic field generated by the magnetic tiles interacts with the alternating magnetic field of the stator winding, driving the rotor to rotate and thereby driving the compressor piston to complete the refrigerant circulation. Indoor and outdoor fan motors Whether it is an axial fan or a cross-flow fan, their driving motors also adopt permanent ferrite magnetic rings. Compared with traditional induction motors, the permanent magnet solution can increase efficiency by more than 10% while reducing noise by 3 to 5 dB(A). Electronic expansion valve and stepper motor The micro stepping motor is also equipped with injection-molded ferrite multi-pole magnetic rings inside, which are used to precisely regulate the refrigerant flow and achieve a temperature control accuracy of 0.1℃. Energy conservation: The high residual magnetism (Br≥ 4.2kG) and high intrinsic coercive force (Hcj≥ 4.0kOe) of permanent ferrite magnetic tiles enable the motor to still output high torque at low speeds. Combined with frequency conversion algorithms, the annual energy consumption efficiency (APF) can be increased by 15% to 20%, helping air conditioners easily meet the new national standard level 1 energy efficiency. After the magnetic tile waveform undergoes laser micro-grinding, the cogging torque decreases by 30%, the vibration of the compressor operation is significantly reduced, and the noise of the indoor unit can be as low as 18 dB(A), almost imperceptible. The Curie temperature of ferrite can reach up to 450 ℃. It will not demagnetize even when working for a long time in an environment ranging from -30 ℃ to 120 ℃, ensuring the stable operation of the air conditioner in both extremely cold and hot weather. From fixed-frequency to variable-frequency, from energy-saving to quiet, although the permanent ferrite magnetic tiles are hidden deep in the compressor, they dominate every "breath" of the air conditioner. It not only makes the electricity bill thinner but also makes summer nights quieter - this is precisely the irreplaceable value of permanent ferrite magnets when air conditioners are in operation.

The performance of sintered magnets is close to that of the FB9 series, and their strength is superior to that of traditional sintered magnets. This high-performance material not only meets the requirements of magnetic tiles for permanent magnet DC motors in new energy vehicles, but also expands its application in downstream industries such as home appliances and speakers. 2. Innovation in the integration of permanent magnets and magnetoresistance In the motors of new energy vehicles, the optimization of permanent magnet synchronous motors and reluctance motors is the focus of current technological development. For instance, Toyota's newly developed "bipolar magnetic circuit rotor" has increased the magnetic energy product by 10% and reduced the use of rare earths by 20% through magnetic circuit optimization. In addition, the BMW iX3 adopts a permanent magnetic-assisted synchronous magnetoresistive solution, which increases the proportion of magnetoresistive torque to 60%, achieving a system efficiency of 92% while reducing the reliance on rare earths. 3. Development of rare earth-less and rare earth-free permanent magnet motors To reduce reliance on rare earth resources, the research and development of rare earth-less and rare earth-free permanent magnet motors has become a hot topic in the industry. For instance, the design of the combined excitation external rotor permanent magnet motor proposed by the S. Ishii team from Tohoku University in Japan combines rare earth permanent magnets with ferrites. This not only reduces the amount of rare earth used by 50% but also significantly improves the torque performance. In addition, the W. Kakihara team significantly enhanced the motor's anti-demagnetization capability by adopting a spoke rotor structure with magnetic clustering function and increasing the amount of ferrite used. 4. Multi-layer V-shaped magnetic steel layout and laser welding process To suppress the eddy current loss during high-speed operation, a certain brand has applied a five-layer V-shaped magnetic steel embedding technology, reducing the generation of eddy currents through multi-segment magnetic pole division. In combination with the laser welding process, the bonding strength between the rotor core and the magnetic steel has been increased by 30%, ensuring the reliability of the 200KW-class motor under extreme working conditions. 5. Application of Axial Flux motors Axial flux motors have gradually been applied in new energy vehicles due to their small size and high efficiency. For instance, the axial flux design of YASA reduces the volume by 50% compared to radial motors and is compatible with 800V high-voltage platforms. The promotion of this motor technology will further enhance the performance and energy efficiency of new energy vehicles. 6. The development of electromagnetic and thermal coupling technology The development of electromagnetic thermal coupling technology provides an effective solution to the heat dissipation problem of permanent magnet motors in new energy vehicles. For instance, the magnetic steel cooling structure developed by Jingzhou Shengqi Magnetic Industry Co., Ltd. has enhanced the heat dissipation, stability and reliability of the motor through heat pipes and phase change materials. The application of this technology will effectively extend the service life of the motor and improve the overall performance of the vehicle. The breakthrough in permanent ferrite technology in new energy vehicles not only enhances the performance and efficiency of motors but also reduces the reliance on rare earth resources, promoting the sustainable development of the industry. In the future, with the continuous advancement of technology, permanent ferrite materials will play a more significant role in the field of new energy vehicles, contributing to the further development of the new energy vehicle industry.

In recent years, the importance of the permanent ferrite magnet industry in the global market has become increasingly prominent, but at the same time, it is also facing many international trade challenges. The following is an analysis of the main challenges and their impacts faced by China's permanent ferrite magnet industry in international trade: 1.Tariff policy and trade frictions The adjustment of tariff policies in countries such as the United States has had a significant impact on China's export of permanent ferrite magnets. For instance, the United States has imposed high tariffs on Chinese imports, which has led some enterprises to re-plan their logistics and production layouts to avoid additional costs. This kind of trade friction not only increases the export costs of enterprises, but also hinders the stability of the supply chain and market access. 2. Export control policy The Chinese government has imposed export controls on some medium and heavy rare earth-related items, which has also had an indirect impact on the permanent ferrite magnet industry. Although permanent ferrite magnets themselves are not within the scope of regulation, some of their raw materials may be restricted, thereby affecting the production costs and supply chain stability of enterprises. In addition, the customs system may make misjudgments when implementing policies, resulting in the temporary detention of some products or delays in inspection. 3. Raw material supply and price fluctuations The ferrite permanent magnet industry is highly dependent on raw materials, especially rare earth elements. Geopolitical tensions may lead to disruptions in the supply of key raw materials or price hikes. For instance, China's huge demand for rare earth elements has made it a global focus. If regional conflicts or policy restrictions arise, it will directly affect the production of materials and cost control. 4. Technical Barriers and Intellectual Property Protection Technical barriers and intellectual property protection issues in international trade also pose challenges to the permanent ferrite magnet industry. Some developed countries restrict the entry of Chinese products by setting strict technical standards and patent barriers. This requires Chinese enterprises to increase investment in research and development and enhance the technological level of their products to meet the access requirements of the international market. 5. Market Competition and Brand Building In the global market, the permanent ferrite magnet industry is confronted with fierce competition from other countries and regions. Chinese enterprises still need to strengthen brand building and international market promotion in order to enhance the international recognition and market share of their products. In addition, some small and medium-sized enterprises may encounter difficulties such as backward technology and shortage of funds, making it difficult for them to gain a foothold in the fierce market competition. 6. Requirements for environmental protection and sustainable development With the global emphasis on environmental protection, the permanent ferrite magnet industry is also facing higher environmental protection requirements. Enterprises need to adopt green manufacturing technologies in the production process to reduce pollutant emissions and meet the environmental protection standards of the international market. This not only increases the production costs of enterprises, but also puts forward higher requirements for their technological upgrading and management capabilities.   Facing the above challenges, the permanent magnet ferrite industry in China can adopt the following strategies to enhance its international competitiveness: Technological innovation and R&D investment: Continuously increase R&D investment, enhance product performance and quality, and break through technical bottlenecks. Supply chain optimization: Establish a multi-point procurement and production network to reduce reliance on a single supply source and ensure the stability and flexibility of the supply chain.
