Hiperco 50A 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℃). 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% 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.


Special Motors for the Aerospace Industry (e.g. applications where high magnetic saturation and high strength is required with as little weight as possible); Electromagnets for medical applications (e.g. to focus beams for radiation therapy in medical radiology applications); Electrical Generators; Specialty Transformers (e.g. electrical circuits and magnetic circuits where frequencies must be varied); Pole Pieces for Electromagnets; Magnetic Bearings (e.g. applications where rotating parts are levitated); High Magnetic Flux Devices and Instruments.

Heat Treatment

When selecting a heat treating temperature for the application, two factors should be considered:

  1. For best magnetic soft characteristics, select the highest suggested temperature.
  2. If the application requires specific mechanical properties higher than that produced when employing the highest temperature, select the temperature that will provide desired mechanical properties.

As temperature decreases, magnetic properties become less magnetic soft. Heat treating temperature for best soft magnetic properties should be 1625°F +/- 25°F (885°C +/- 15°C).Do not exceed 1652°F(900°C).

The heat treating atmosphere used must be nonoxiding and noncarburizing. Atmospheres such as dry hydrogen or high vacuum are suggested. Time at temperature should be two to four hours. Cool at a rate of nominally 180 to 360°F (100 to 200°C) per hour to a temperature of least 700°F(370°C), then cool naturally to room temperature.
