Cobalt-based amorphous nanocrystalline alloy ribbon
Cobalt-based amorphous alloys, thanks to their unique microstructure, boast 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 — far surpassing conventional iron-based amorphous materials and silicon steel; - Extremely low coercivity — delivering rapid response and reduced losses. - Cobalt-based amorphous alloys exhibit stable performance across a wide temperature range and at high frequencies, with strong anti-interference capabilities, making them well-suited for precision sensing and high-frequency applications. - Customized products can be tailored to meet specific customer requirements, offering features such as low noise, high sensitivity, and low-loss operation at high frequencies.
Iron-based nanocrystalline ribbon
・It combines high permeability, high saturation magnetic flux density, low coercivity, and low losses, with overall performance far superior to conventional iron-based amorphous alloys, silicon steel, and certain permalloy grades. ・It exhibits excellent frequency adaptability, featuring low losses and high efficiency at medium and high frequencies, making it suitable for a wide range of applications. ・Its cost is significantly lower than that of cobalt-based amorphous alloys, offering outstanding cost-effectiveness. ・It demonstrates excellent thermal stability and reliable, consistent performance, making it well-suited for large-scale industrial applications.
Due to the following characteristics, iron-based amorphous alloys exhibit a significant advantage in low core losses: - Thin thickness—only about one-tenth that of grain-oriented silicon steel; - High resistivity—approximately twice that of grain-oriented silicon steel; - Low coercivity—only about one-third that of grain-oriented silicon steel.
