Metallic Glass Iron/Boron/Silicon Coil (Fe81/B 13.5/Si 3.5/C 2 (Atomic %))

Available in 5 variations, Metallic Glass Iron/Boron/Silicon Coils (Fe81/B 13.5/Si 3.5/C 2 (Atomic %)) are a new product range within our extensive choice of foils. Metallic glasses are amorphous alloys with desirable properties like high strength, elasticity, corrosion resistance and soft magnetic properties. The Iron/Boron/Silicon composition produces a magnetic metallic glass that can be precision cast into thin foils or wire. Creating a coil shape then allows them to be customized for electromagnetic applications. Potential uses for these coils include transformer cores, magnetic shielding and biomedical implants.
