Hysteresis alloys (Iron-Cobalt- Vanadium)
Representive Grades: 2J4, 2J7, 2J10, 2J11, 2J51, 2J52, 2J53
Note:
A ductile, semihard magnetic alloy which has been used in laminations for hysteresis motors. Alloyexhibits highest efficiency
(loss per unit magnetic field strength) of any known material.
Vicalloy I is a cobalt-vandium-iron ductile permanent magnet alloy. The material is used in electrical and electronic applications.Magnetic properties are optimized by heat-treating cold rolled material.
Vicalloy I has a relatively high remanence and low coercive force.
