1J22 FeCo49V2 Soft Magnetic Alloy Round Bar Hiperco 50 Permendur 2.4T High Saturation Rod
1J22 FeCo49V2 Soft Magnetic Alloy Round Bar / Rod
1J22 is an iron-cobalt-vanadium (FeCo49V2) soft magnetic alloy, internationally equivalent to Hiperco 50, Permendur 50A and Supermendur 50A. It is supplied as hot-rolled, forged or cold-drawn round bar with the highest saturation magnetic induction among soft magnetic alloys, making it the preferred core material for aerospace generators, electromagnet pole tips, magnetic bearings, relays and magnetic shielding components.
