Iron Cobalt Alloy Hiperco 50 Chemical Composition: Co49

COBALT-IRON SOFT MAGNETIC ALLOY HIPERCO 50

HIPERCO 50 is a high saturation magnetic induction strength iron cobalt vanadium soft magnetic alloy. In the existing soft magnetic materials, the alloy has the highest saturation magnetic induction 2.4T and a high Curie point 940 C. Due to the high saturation magnetic induction, when manufacturing a motor of the same power, the volume can be greatly reduced, and the weight can be reduced, which is less than 50 Percent of that of an ordinary motor. Moreover, the motor has high sensitivity, low heat generation, good stability and long life. Due to the high Curie point, the alloy can be operated at higher temperatures where other soft magnetic alloy materials have been completely demagnetized and maintain good magnetic stability. The performance stability of the motor is better than that of the permanent magnet motor at higher operating temperatures.

The alloy is melted using Vacuum Induction Melting VIM techniques.

FURTHER PROCESSING (Heat Treatment)

A final heat treatment (magnetic final annealing) is mandatory for achieving the magnetic and mechanical properties. The necessary growth of the grains in the material, and hence the accompanying improvement in the characteristic magnetic values, only occurs during the final annealing.

The maximum magnetic properties of HIPERCO 50 are best achieved by annealing for 5 hours at 865 C to 875 C in a pure dry hydrogen atmosphere (-40 C dew point). Cooling in the blow 870 C to 750C range at 50C per hour and 750C to 300C at 200C per hour is recommended. In order to retain the maximum properties this anneal should be done after all manufacturing of the part is completed.

XAGY does not sell HIPERCO 50 products in the (magnetic) annealed condition.but we are provide the option of heat-treatment processing techniques and Recommendations!
