Magnetic Shielding Alloy Tube (Ni77/Fe14/Cu 5/Mo 4) is a nickel-iron soft magnetic alloy tube available from Goodfellow's range of tubes. It has very high permeability and low coercivity, making it extremely effective for shielding against static or low-frequency magnetic fields. With 7 variations, Goodfellow's Magnetic Shielding Alloy Tubes (Ni77/Fe14/Cu 5/Mo 4) are ideal for applications such as shielding of sensitive electrical components, sensors, and scientific instrumentation against external magnetic interference. The specialized magnetic properties of MuMetal® Alloy enable effective magnetic shielding in compact, lightweight forms.
