Details

SKU: 1000071197 Product Code: NI03-FL-000171
Magnetic Shielding Alloy Foil (Ni77/Fe14/Cu5/Mo4) is a highly permeable, soft magnetic material designed for efficient suppression of external magnetic interference across a wide range of frequencies. Its optimized balance of nickel, iron, copper, and molybdenum provides low coercivity, stable resistivity, and strong shielding capabilities, particularly after magnetic annealing treatments that enhance local atomic ordering. This foil is extensively used in aerospace, precision instrumentation, and electronics industries, where high-performance magnetic shielding is essential. Specific applications include lining enclosures for satellite payloads, constructing protective layers in superconducting devices, and stabilizing sensitive quantum or photonic measurement setups. Research emphasizes its role in developing next-generation shielding materials tailored for ultra-low-frequency and cryogenic applications. Magnetic Shielding Alloy Foil (Ni77/Fe14/Cu5/Mo4) thus plays a pivotal role in advancing reliable performance and measurement precision, making it indispensable in both scientific innovation and industrial technology.
