Cobalt-based amorphous nanocrystalline alloy strip

Cobalt-based amorphous alloys, owing to their unique microstructure, exhibit core advantages such as ultra-low losses and exceptionally high permeability: • Near-zero magnetostriction—ensuring noise-free operation and distortion-free signals; • Ultra-high permeability—significantly superior to conventional iron-based amorphous materials and silicon steel; • Extremely low coercivity—resulting in rapid response and reduced losses. • Cobalt-based amorphous alloys maintain stable performance across a wide temperature range and at high frequencies, with strong anti-interference capabilities, making them well-suited for precision sensing applications and high-frequency operating conditions. • Customized products can be provided to meet specific customer requirements, offering tailored performance characteristics such as low noise, high sensitivity, and low-loss operation at high frequencies.

Amorphous Nanocrystalline Strip

Amorphous strip material is a new type of functional material characterized by a unique atomic structure and outstanding comprehensive performance. It primarily consists of elements such as iron, silicon, and boron. This material exhibits excellent properties including low coercivity, high magnetic permeability, high resistivity, resistance to high-temperature corrosion, and high toughness.

Iron-based nanocrystalline strip

・Combines high permeability, high saturation magnetic induction, low coercivity, and low losses, delivering overall performance that significantly outperforms conventional iron-based amorphous alloys, silicon steel, and certain permalloy alloys; ・Exhibits strong frequency adaptability, with low losses and high efficiency at medium to high frequencies, making it suitable for a wide range of applications; ・Costs substantially less than cobalt-based amorphous alloys, offering exceptional cost-effectiveness; ・Demonstrates excellent temperature stability and reliable, consistent performance, making it well-suited for large-scale industrial applications.
