Permendur is an alloy created by mixing 48-50% cobalt with iron (up to 2% vanadium can be added). The alloy was invented in the United States around 1920. It has a high permeability at high flux densities with a very high saturation point. Its magnetic transition temperature is 980 °С. Its name in Russian is пермендюр (49К2ФА).
