rare earth Magnetic material

 rare earth Magnetic material,Alnico with many shapes, sizes and colors.
 

Cast Alnico can be processed to be intricate and complex shapes to meet customers demand.Some types of Alnico are isotropic, meaning they can be efficiently magnetized in any direction. Other types, such as Alnico 5 and Alnico 8 are anisotropic, meaning they have a preferred direction of magnetization, orientation. Anisotropic magnets generally have a greater magnetic capacity in their preferred orientation than isotropic. Anisotropic Alnico magnets are oriented by heating them above a critical temperature, and cooling them in the presence of a magnetic field.

1) Magnetic properties are very stable in change of temperature (-0.02% / °C for
Br)
2) Magnetic properties are steady in prolonged use
3) The uniformity for magnetic properties is excellent
4) Because of the high coercive force, the demagnetization to external magnetic field
is very small
