Cobalt-based amorphous nanocrystalline alloy strip

Thanks to their unique microstructure, cobalt-based amorphous alloys boast core advantages such as ultra-low losses and ultra-high permeability: • Near-zero magnetostriction—resulting in noise-free operation and distortion-free signals; • Ultra-high permeability—far superior to conventional iron-based amorphous alloys and silicon steel; • Extremely low coercivity—offering highly sensitive response and lower energy losses. Cobalt-based amorphous alloys demonstrate stable performance across a wide temperature range and at high frequencies, with strong anti-interference capabilities, making them ideal for precision sensing and high-frequency applications. We can tailor products to meet specific customer needs, offering customized solutions with features such as low noise, high sensitivity, and low losses at high frequencies.
