Magnetic Shielding Alloy ASTM A753 Alloy 4
ASTM- A- 753, Alloy 4
A.K.A. Hipernom, Hy Mu 80, Moly Permalloy, Magnifer 7904; is a soft magnetic nickel-iron alloy with about 80 % nickel, 4.2 – 5.2 % molybdenum, a saturation induction of approximately 8,000 Gauss, the highest technically obtainable permeability,( Max >350,000) and a very low coercive force.
Alloy 4 exhibits very high permeability at very low induction, yielding superior magnetic shielding attenuation of low flux density magnetic fields.
