What is Hiperco50 alloy?
Hiperco50 is a Cobalt-Iron soft magnetic alloy with equal parts of cobalt and iron . The alloy was invented in the United States around 1920 . Standard Hiperco50 compositions coined Fe-Co 50/50 or 50Fe-50Co may contain carbon up to 1% while a composition patented in 1932 named Vanadium hiperco50, Permendur 2V and recently offered by Good fellow Corp. under the name hiperco50A 49(all of which are 49Fe-49Co-2V) contains 2% vanadium for better mechanical properties and ease of machinability. Carpenter Technologies produced a similar alloy formerly coined Supermendur and2V-Permendur renamed recently Hiperco 50, and its latest formulation comprises typically same amounts of cobalt, iron and vanadium but with additional trace amounts of niobium , silicon and manganese for even better ease of forgeability and cold forming. Vacuumschmelze produces 48%...50% Cobalt alloys, named VACOFLUX(R) and VACODUR(R). 50Fe-50Co and 49Fe-49Co-2V alloys all have high permeability with little loss and highest flux densities at saturation point (saturation induction is around 2.3-2.4 Tesla) available amongst commercial soft magnetic alloys. Its magnetic transition temperature is 980 °С . Its name in Russian is пермендюр (49К2ФА).
