Hiperco---A Magnetic Alloy

Hiperco alloy is an improved ironcobalt alloy specifically developed for electric machinery applications, where weight or space is at a premium. The basic composition is 34.5-35.5 per cent cobalt with an alloying element such as chromium added to improve hot and cold workability and increase electrical resistance Processes have been developed whereby the alloy can be cold rolled to any desired gauge. Because of its high magnetic saturation value (over 12 per cent higher than that of iron), its unusually high permeability for magnetizing forces in the range H = 10 to H = 400 oersteds, and because of its low losses at high inductions, Hiperco alloy will enable manufacturers to produce motors and generators considerably lighter in weight than by using present standard materials.
