For the applications where high flux density at minimum weight is a prerequisite, designers’ first choice is 50% Cobalt Iron alloy. It has very high magnetic saturation (up to about 2.3 T) and low coercivity.
Besides very precise stamping process, components made in Cobalt Iron need comprehensive hydrogen heat treatment process which enhances Magnetic performance. Magnetic and Physical properties are optimized as per application needs with variation in annealing temperature.
General applications of the Cobalt Iron Alloy include Stator and Rotor lamination for Aircraft Engines, Motors etc…
