Permalloy 80 Core
Description
Permalloy 80 is a highly magnetic nickel-molybdenum-iron alloy, with roughly 80% nickel and 15% iron and 5% molybdenum content. It's useful as a magnetic core material in electrical and electronic equipment. Permalloy 80 provides high initial and maximum permeabilities with low coercive force, low hysteresis loss, low eddy-current losses, and low magnetostriction which is critical for industrial applications.
Application
Transformer laminations; Relay;Recording Heads;Deflection and Focusing Yokes; Amplifiers;Loudspeakers;Shielding.
