Description

An alloy of 49% cobalt, and 2% vanadium, balance iron, Hiperco 50 and Hiperco 50A have the highest magnetic saturation of all soft-magnetic alloys and excel in applications where this attribute is needed. Hiperco 50 maintains its strength after heat treating making it your best choice for applications that experience high forces (e.g. rotating parts).
