Mu Metal ,a Nickel-Iron-Molybdenum alloy, provides high initial and maximum permeabilities with low coercive force, low hysteresis loss, low eddy-current losses, and low magnetostriction at low field strengths. This vacuum-melted product also offers the advantages of small size and weight in magnetic core and shielding materials for the applications shown below. • Transformer laminations • Relays • Recording Heads • Deflection and Focusing Yokes • Amplifiers • Loudspeakers • Shielding Typical D.C. Magnetic Properties: Saturation Flux Density: 7,500 gausses Coercive Force from H = 1 oersted: 0.015 oersted Residual Induction: 3,700 gausses Hysteresis Loss from Saturation: 9 ergs/cm3/cycle Permeability @ B = 100: 75,000 Maximum Permeability: 300,000 (After appropriate anneal)
