Working Principle

AlNiCo is mainly composed of aluminum, nickel and cobalt, and has excellent temperature stability and high residual magnetic flux density. It has high magnetic properties and is made by casting or sintering.Cast magnets can create complex shapes that other magnets cannot, such as horseshoes. Sintered AlNiCo has slightly lower magnetic properties but better mechanical properties.
