Metallic Glass Iron/Boron/Silicon Spooled Wire (Fe77.5/B15/Si7.5 at%)

Metallic Glass Iron Boron Silicon Spooled Wire (Fe77.5/B15/Si7.5 atomic) combines high magnetic permeability, excellent corrosion resistance, and thermal stability in a continuous wire format optimized for winding applications. The amorphous structure reduces core losses and enhances uniform magnetic response, making it ideal for coil windings, transformer components, and high-frequency inductors. Its boron and silicon additions improve glass stability and enable consistent performance under cycling conditions. Industries such as aerospace, electronics, and renewable energy use this wire for compact magnetic cores, EMI suppression, and power conditioning systems. Applications include fine-gauge inductors, energy-efficient transformers, and precision sensor windings. Research explores processing conditions for amorphous wires, domain structure tuning for high-frequency applications, and alloy stability during extended service. The spooled format ensures continuous supply, flexible winding, and reproducibility, reinforcing its importance in industrial electromagnetic technologies and research on amorphous Fe-based alloys.
