Sintered NdFeB Magnet

Coming out in early 1980s, NdFeB permanent magnetic material is now widely applied in information industry, defense industry, automobile industry, wind power home appliance, instruments and apparatus, medical equipment, and magnetic instruments, etc.. Its main constituent is Nd2Fe14B, which has high magnetic performance. Its maximum energy density(BHmax) is over 10 times as high as that of ferrite magnet; maximum working temperature up to 250 centigrade. Also, it has good mechanical behavior, which makes it suitable for different processing modes, such as grinding, wire cutting, drilling, etc. Due to its poor performance in anti-corrosion, it must be treated with different coatings tailored to specific need (eg, Zn, Ni, Au, Epoxy, etc.).

    NdFeB magnet is prepared by powder metallurgy. Its main metallographic phase  is Nd2Fe14B. Currently, this magnetic material has the highest magnetic performance. Its strengths include strong anti-demagnetization, and high cost-effectiveness, while its drawbacks include temperature dependence and weak anti-corrosion. However, with proper treatment of coating or plating, and by selecting product of different coercive force under different circumstances, NdFeB magnet could basically meet the requirement of different customers.
