NdFeB Rare Earth Magnets
The third-generation rare earth material, known for exceptional magnetism and cost-efficiency. Used in motors, automotive (wipers, starters), wind energy, speakers, VCMs, aerospace, MRI, and magnetic components.
Ferrite Magnets
Widely applied due to low cost. Used in DC motors, automotive motors (seats, fuel pumps), magnetic separators, headphones, and microwave ovens.
In the motor industry, numerous components utilize magnets, leading to the use of various magnet types. These include rare-earth NdFeB magnets, ferrite magnets, samarium-cobalt permanent magnets, and rubber magnets, as well as magnetic assemblies composed of these materials. Applications span VCM (Voice Coil Motors), CD/DVD-ROM drives, generators, electric motors, servo motors, micro-motors, standard motors, and vibration motors, among others.
With the rapid development of new energy vehicles (NEVs), the market penetration rate of NEVs is continuously increasing. In NEVs, many components require NdFeB magnets, such as drive motors, hub motors, electric power steering motors, electronic brake motors, fan motors, window motors, seat adjustment motors, and vehicle audio systems.
Magnets are essential components in numerous industrial machines and equipment, including: magnetic separators, magnetic separators, magnetic lifters, magnetic machinery, magnetic latching relays, sensors, etc. Without magnetic materials, electrification would be impossible.
~15% of rare-earth magnets are used in devices like loudspeakers, microphones, pickups, stage/ car audio, hearing aids, headphones, telephones, and sensors. These electroacoustic devices share a common principle: current through a voice coil in a magnetic air gap causes vibration, which drives a diaphragm to produce sound.
Many sectors within the packaging industry rely on magnets, such as: luggage magnets, leather goods magnets, toy magnets, packaging for handicrafts and gifts, cosmetic packaging, etc.
Magnets are widely used across industries. Beyond those mentioned, applications include: electronics & appliances (permanent magnet vacuum circuit breakers, magnetic latching relays, electricity meters, water meters), healthcare (MRI machines, medical devices, magnetic therapy), and daily products (reed switches, sensors, magnetic fixtures, automatic mahjong machines, magnetic locks, door/window magnets).
