Iron Cobalt Alloy Permendur 49 Chemical Composition: 49%cobalt

COBALT-IRON SOFT MAGNETIC ALLOY PERMENDUR 49

PERMENDUR 49 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 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 PERMENDUR 49 are best achieved by annealing for 5 hours at 1150 C to 1155 C in a pure dry hydrogen atmosphere (-40 C dew point). Cooling in the blow 1150 C to 870 C range at 50 C per hour and 870 C to 750 C at 50 C per hour,750 C to 300 C at 200 C/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 PERMENDUR 49 products in the magnetic annealed condition.but we are provide the option of heat-treatment processing techniques and Recommendations!
