AlNiCo magnets have a low coercive force that limits their applications in many cases. Casting and sintering are two major processes used to manufacture the AlNiCo magnets.
\nAlnico Magnets has very good resistance to corrosion and high max working temperature, which can reach 550deg.C. They are widely used in high stability fields as military, aerospace, automobiles, and security system etc. Even if other materials offer higher energy and coercivity values, the huge remanence and thermal stability of Alnico magnets make it the ideal cost-effective material for certain applications.
