Description
An alloy of 49% Cobalt,and 2%Vanadium, balance Iron,Hiperco 50A have the highest magnetic saturation of all soft-magnetic alloys and excels in applications where this attribute is needed.
Hiperco 50A alloy is a soft magnetic alloy which has been used primarily as magnetic core material in electrical equipment requiring high permeability values at very high magnetic flux densities.
Application
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:
For best magnetic soft characteristics, select the highest suggested temperature.
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.
