AlNICo Magnet

AlNiCo magnet is a alloy composed by Al, Ni, Co, Fe and other little metal elements, including Sintered AlNiCo and Cast AlNiCo.

Casting process can make into AlNiCo with different sizes and shapes; sintered products are limited to small size and lower property, 

while its dimension tolerance and machinability are better.

The advantages of the AlNiCo magnet are its high remanence and low temperature coefficient which is 1.35T and -0.02%/℃.And 

the maximum working temperature can reach to 520℃ or so. The disadvantages are .But the AlNiCo magnet has a very low coercive 

force (Hcb) and nolinear demagnetizing curve. So, though AlNiCo magnet is easy to be magnetized, it is also easy to be demagnetized..
