Magnetic Shielding Alloy Spherical Powder (Ni77/Fe14/Cu 5/Mo 4)

Magnetic Shielding Alloy Spherical Powder (Ni77/Fe14/Cu 5/Mo 4) is a soft magnetic alloy with high permeability that we produce as part of our extensive range of specialty metals. With 11 variations available, this nickel-iron alloy powder is valued for its very high initial and maximum permeability, low coercivity, and high saturation induction. These exceptional magnetic properties make MuMetal® Alloy Spherical Powder ideal for applications like electromagnetic interference (EMI) shielding for sensitive electrical components, as well as transformer cores and inductors. This material’s spherical morphology also provides advantages for powder pressing and compaction.
