ASTM- A- 753, Alloy 2
A.K.A. Hi Perm 49, Hipernik, Alloy 50, is a soft magnetic nickel-iron alloy with about 50 % nickel, 50% Iron, with a saturation induction of approximately 12,500 Gauss, an initial permeability of 40,000 and a maximum permeability of 150,000.
Alloy 2 exhibits high permeability at low induction, yielding adequate magnetic shielding medium to high flux density magnetic fields.
Additionally, Alloy 2 cold works extremely well.
