79HM Soft Magnetic Alloys For Magnetic Shielding High Initial Permeability
79HM Soft Magnetic Alloy for Magnetic Shielding High Initial Permeability
79HM 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. 79HM 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.
