We serve industries needing superior magnetic shielding capabilities, with a focus on advanced metal solutions. Using high-permeability alloys, our Mu-Metal Foil is expertly crafted to protect delicate electronic devices from magnetic interference. Our foils offer outstanding performance and dependability for applications in electronics, aerospace, medicine, and defence. At Kunj, we prioritise accuracy, quality, and personalisation to satisfy particular customer demands. We guarantee that our Mu-Metal Foils satisfy international standards for both industrial and scientific applications through effective production and stringent quality control.
The main constituents of Mu-Metal Foil are 77–80% nickel, 4–5% molybdenum, and the remaining iron; trace elements are added for improved magnetic properties. It is renowned for its exceptional attenuation of low-frequency magnetic fields, low coercivity, and extraordinarily high magnetic permeability. Mu-Metal Foil is easily formed into intricate shapes and is ductile and soft. Tensile strengths typically fall between 350 and 500 MPa, indicating a moderate level of mechanical strength. After forming, it needs to be annealed in a hydrogen atmosphere to regain its best permeability and magnetic shielding capabilities.
