Hiperco 50 is a soft magnetic alloy which has been used primarily as magnetic core material in electrical core material in electrical equipment requiring high permeability values at very high magnetic flux densities.
The magnetic characteristics of this alloy permit weight reduction, reduction of copper turns, and insulation in the end product when compared to other magnetic alloys having lower permeabilities in the same magnetic field range.
Heat Treatment
When selecting a heat treating temperature for the application, two factors should be considered:
1. For best magnetic 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. Heat treating temperature for best 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.
