sintered NdFeb permanent magnet

Sintered Ndfeb Permanent Magnet material is an alloy magnet composed of neodymium, iron, boron and other trace elements (Dy, Al, Nb, Ga, Mo, Co, etc.). Its manufacturing through powder metallurgy process will be melted alloy ingot powder orientation in the magnetic field and molding, forming the embryo body in inert gas or vacuum sintering to densify, so the sintered Ndfeb has high magnetic energy product and coercivity, and cost-effective, and has good mechanical characteristics of the "contemporary magnetic king" said.

Sintered Neodymium Magnets is also called rare earth permanent magnet, the main component is rare earth metals. Rare earth metals belong to the strategic reserve resources in our country. The storage of rare earth in our country accounts for more than 90% of the world, which is mainly distributed in the Inner Mongolia Baitou Baiyun deposit Hubei, Jiangxi Ganzhou region, Sichuan and guizhou regions. Nowadays 70% of the Magnetic Material is produced in our country, which sintered ndFeb material was also produced in our country.

Application fields of sintered NdFeb:
Sintered NdFeb is mainly used in all kinds of DC motor, brushless motor, stepper motor, servo motor, permanent magnet motor, automobile motor, motorcycle motor, electric tool motor, household appliance motor, office equipment motor, elevator pull motor, oil pump, water pump, digital camera, vibration motor, monitoring equipment, speaker sound, instruments, generators, wind power generation, sports equipment , massage equipment, electronics industry, hardware and plastic, printing and packaging, craft gifts, aquarium equipment, locks, kitchen and bathroom supplies, lighting, stationery, toys, wood art products...... And so on.
