Alnico
cact magnet
Alnico cact magnet is composed mainly of Al, Ni, Co,
Ti, Cu, and Fe. It is featured in a wide range of uses because of its
high magnetic flux density and extreme stability under changing temperature
conditions. Alnico cast magnet are available as either isotropic or anisotropic,
with the latter in greater use than the former owing to its coercive force.
