It is the step responsible for the transformation of particulates to net-shaped bodies with the desired properties. WebAlnico magnets have a high coercivity and high Curie temperature. However, Alnico magnets are hard and brittle and cannot be cold worked. They must be made by casting or sintering procedures. Alnico magnets can generate a magnetic field up to 0.15 Tesla. Let’s take an intermediate anisotropic cast aluminum-nickel-cobalt alloy as an example. chipmunk\u0027s xy
