SOFT MAGNETIC ALLOY - HYMU 80 : (Composition (Nominal) 0.02 C, 0.50 Mn, 0.35 Si, 80.00 Ni, 4.20 Mo, Bal. Fe ; ( HYMU 80 is an alloy of nickel, iron and molybdenum. It is a soft magnetic alloy with exceptionally high magnetic permeability. The alloy has a low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction is critical for industrial applications,where variable stresses in thin films would otherwise cause a ruinously large variation in magnetic properties. ) : (SPECIFICATION :ASTM A753 ; (Product availability and request a QUOTE!
