Vicalloy Iron-Cobalt- Vanadium Hysteresis alloy strip made in China
Vicalloy is a family of cobalt-iron-vanadium wrought permanently magnetic alloys. Vicalloy is precipitation hardened and can be formed by a number of cold working techniques. It is commonly used in electromechanical device applications, such as Wiegand wires because it shows a large Wiegand effect.
| Hysteresis alloys (Iron-Cobalt- Vanadium)
Representive Grades: 2J4, 2J7, 2J10, 2J11, 2J51, 2J52, 2J53 |
|
Note:
A ductile, semi-hard magnetic alloy which has been used in laminations for hysteresis motors. Alloy exhibits 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.
