Mu-Metal foil is primarily composed of about **77-80% nickel**, **15-20% iron**, with small amounts of copper (~4–6%) and molybdenum (~2–4%) added to improve its magnetic softness and permeability. It contains very low carbon and trace impurities to maintain its magnetic performance. Mechanically, the foil boasts high tensile strength (~500-700 MPa), good yield strength (~250-350 MPa), and elongation values between 30-40%, making it both strong and ductile enough to be shaped into thin shielding foils. After annealing, its permeability can reach impressive levels, with low coercivity and minimal hysteresis losses.

Mu-Metal foil from Marsh Nickel Alloys is ideal for applications that require protection from static or low-frequency magnetic fields, such as enclosures for sensitive electronics, magnetic resonance imaging (MRI) systems, laboratory instruments, and sensor components. It’s also utilized in transformer cores, magnetic shielding for audio equipment, and precision devices where external magnetic interference could compromise performance. With its high permeability and excellent formability, Mu-Metal foil is a top choice for these critical applications.
