Material Notes: Iron content calculated as remainder.
Hiperco® alloy 50 is an iron-cobalt-vanadium soft magnetic alloy which exhibits high magnetic saturation (24 kilogauss), high D.C. maximum permeability, low D.C. coercive force, and low A.C. core loss. This alloy is produced in strip form only and contains a small niobium addition for grain refinement during mill processing and final heat treatment of strip.
Hiperco alloy 50 strip has been used primarily in the manufacture of rotor and stator laminations in motors and generators for aircraft power generation applications. These laminations are stamped from cold rolled strip and must be final annealed in a protective atmosphere or vacuum environment at a temperature which will provide and optimum combination of mechanical and magnetic properties to withstand the high stresses encountered in service.
Hiperco 50 has the same nominal composition as Vanadium Permendur and Permendur V.
