Hiperco 50 HS is an iron-cobalt-vanadium soft magnetic alloy that exhibits high magnetic saturation (24 kilogauss) and a unique combination of high yield strength and moderate core loss. The alloy contains a niobium addition for grain refinement during mill processing and final heat treating to produce higher yield strength than conventional Hiperco 50. Key benefits of this alloy are:
Hiperco 50 HS strip should be considered a candidate for use in the manufacture of rotor laminations for aircraft power generation applications and for high-speed motors. These laminations are stamped from cold rolled strip and must be final annealed in a protective atmosphere or vacuum environment at a temperature that will provide an optimum combination of magnetic and mechanical properties to withstand the high stresses encountered in service.
