Hiperco® 50

UNS #R30005

Hiperco® 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® 50 alloy is used primarily for rotor and stator laminations stamped from cold rolled strip and final annealed in a protective atmosphere or vacuum environment at a temperature which will provide an optimum combination of mechanical and magnetic properties to withstand the high stresses encountered in service. Carpenter Technology provides Hiperco® strip, as well as end to end stator and rotor stack production.
