Sintered NdFeB magnets with lowest reversible temperature coefficient

2 Ferrite Sintered NdFeB magnets: it is the main raw material including BaFe12O19 and SrFe12O19. By law made ​​of ceramic , texture rather hard, is a brittle material, due to the ferrite Sintered NdFeB magnets have good temperature resistance , low price, moderate performance , has become the most widely used permanent Sintered NdFeB magnets body .

3 alnico Sintered NdFeB magnets: is made of aluminum , nickel , cobalt , iron and other trace metal elements in an alloy . Casting process can be processed into different sizes and shapes , workability is very good. Cast Alnico permanent Sintered NdFeB magnets with lowest reversible temperature coefficient, operating temperature up to 600 degrees Celsius. Alnico permanent Sintered NdFeB magnets are widely used in a variety of instruments and other applications.

4 , samarium cobalt (SmCo) divided according to different ingredients SmCo5 and Sm2Co17. Because the material is expensive and their development is limited. Samarium cobalt (SmCo) as a rare earth permanent Sintered NdFeB magnets, not only has a high Sintered NdFeB magnets can plot (14-28MGOe), reliable coercivity and good temperature characteristics . Compared with NdFeB Sintered NdFeB.
