ATI Allegheny Ludlum Moly Permalloy Electrical Alloy

An alloy with exceptionally high magnetic permeability, very low coercive force, very low core losses, and low reminance by magnetic field annealing. The alloy finds application in magnetic shielding where fields much less than the Earth's magnetic filed are required. The highest volume applications using laminations or tape wound cores today are ground fault interrupter and modem transformer cores. The alloy is used as well in a variety of other high performance transformer core applications such as tape recorder heads and audio transformers. Control of the cooling rate during heat treatment and superimposition of various customer bake treatments are used to develop the most suitable magnetic quality for the application.Information provided by Allegheny Ludlum
