Amorphous Alloy Magnetic Shielding Sheets
Amorphous alloy magnetic shielding sheets are manufactured from iron-based amorphous alloys, primarily composed of iron (Fe), nickel (Ni), silicon (Si), and other alloying elements. They feature high saturation magnetic flux density (1.4–1.7 T), high magnetic permeability, low coercivity, low excitation current, and low core loss, offering significantly better soft magnetic performance than conventional silicon steel. These magnetic shielding sheets effectively suppress magnetic interference in applications such as NFC antennas and active styluses, while improving magnetic field uniformity and signal stability.
Product Features
01
Excellent flexibility with an ultra-thin profile, available in thicknesses as low as 30 μm (including adhesive).
02
Easily die-cut into various shapes to meet diverse application requirements across a wide range of applications.
03
High saturation magnetic flux density combined with high magnetic permeability, delivering outstanding magnetic shielding performance.
