Alloy 79

alloy 79 soft magnetic shielding magnifer 7904 hymu hipernom moly-permallo

We stock Alloy 79 which is 80% Nickel, 5% Molybdenum, and balance Iron. Alloy 79 is often used in applications where extremely high initial & maximum permeability and minimum hysteresis is needed. Alloy 79 is sometimes referred to by various trade names including Magnifer 7904®, HyMu 80®, Hipernom®, Moly-Permalloy, and Permalloy 80®.

EFI stocks Alloy 79 in rod from diameters of 0.140" to 1.625", in annealed sheet from thicknesses of 0.010" to 0.125", and in annealed strip/coil from thicknesses of 0.004" to 0.025".

More details on Alloy 79 including typical DC & AC magnetic properties, physical & mechanical properties, chemistry and specifications can be found here: Alloy 79 Properties.

Alloy 50

alloy 50 high permeability low core loss soft magnetic shielding alloyWe also stock Alloy 50 which is 49% Nickel and balance Iron. Alloy 50 is often used where high initial permeability, maximum permeability, and low core loss is needed. Alloy 50 is sometimes referred to as Alloy 47-50 and by the trade names Magnifer 50®, and Carpenter High-Permeability 49.

EFI stocks Alloy 50 in rod from diameters of 0.250" to 4.00", in square bar from widths of 1.030" to 2.030" & High-Permeability 49 FM square bar from widths of 1.781" to 2.440", and in annealed strip/coil from thicknesses of 0.002" to 0.050" and rotor grade strip/coil from thicknesses of 0.007" to 0.014".
