Metallic Glass Iron/Boron/Silicon Spooled Wire (Fe77.5/B 15/Si 7.5 (Atomic %)) is an amorphous metal alloy offered in Goodfellow's range of specialty wires. With 38 variations, these metallic glass wires combine high strength, hardness, and elasticity with the pliability of conventional metals. Their unique disordered atomic structure imparts corrosion resistance and magnetic properties. Metallic glass wires find use in applications like transformer cores, high-performance springs, and wear-resistant coatings.
