The AlNiCo magnet mainly have two classification, the sintered AlNiCo and Cast AlNiCo magnet.
The picture is the Cast AlNiCo magnet, it was manufactured by Cast metallurgy technology.
It was applied to many different fields.
Features of Cast Alnico magnet:
1, Vast range of complex shapes and sizes at an economical cost.
2, Ideal for high temperature application up to 550
3, Good corrosion resistance.
4, Density ranging from 6.9g/cm3 to 7.39/cm3
5, A typical hardness of 50 Rockwell C,only suitable for grinding
6, Individual tailored products possible
Application: applied to automobile parts,instruments,audio apparatus,electronic motors,educational equipment aerospace equipment and so on.
