Formula: Ni 77/Fe 14/Cu 5/Mo 4
Form: Coil
Material: Nickel/Iron/Molybdenum (MuMetal)
Commodity: Alloys
Magnetic Shielding Alloy Coil (Ni77/Fe14/Cu5/Mo4) is a high-permeability alloy engineered to provide superior attenuation of external magnetic fields. Its composition of nickel, iron, copper, and molybdenum ensures optimized electrical resistivity, excellent magnetic softness, and enhanced stability under annealing. These properties make it indispensable in industries such as aerospace, electronics, medical imaging, and precision instrumentation, where electromagnetic interference must be minimized. Specific applications include shielding enclosures in MRI systems, transformer cores, and sensitive measurement devices that demand field stability. Research highlights its role in tailoring atomic order and magnetostriction behavior, critical for improving shielding efficiency. The alloy’s importance extends to the innovation of next-generation magnetic shielding solutions, combining mechanical robustness with electromagnetic performance. Magnetic Shielding Alloy Coil (Ni77/Fe14/Cu5/Mo4) is thus of enduring value in both scientific research and industrial technology, ensuring accuracy, safety, and performance in advanced applications.
