Product Description

Hysteresis Alloy 2J4 Iron-Cobalt- Vanadium Permanent Magnetic Alloy



2J4 is a Iron-Cobalt-Nickel-Vanadium hysteresis alloy which combines the advantage of high hysteresis loss and low magnetizing force.

It exhibits the highest efficiency(loss per unit magnetizing force) of any known material. That is why it is widely used in hysteresis motor applications.


The working temperature of 2J4 is higher, and the magnetic properties of 2J4 alloy will not be reduced in the range of + 150-140°C. Among all kinds of hysteresis alloys, 2J4 is a kind of hysteresis alloys with long application time and large dosage.


XUNSHI could supply 2J4 hysteresis alloy precision cold rolled strip, thickness range of 0.05-1.0mm, mature technology, stable quality. After years of exploration and practice, the production technology of hysteresis alloy 2J4, 2J9, 2J10 series products is more perfect. Our R&D center has the most authoritative experts of domestic 2J4, 2J9 and 2J10 products. It can provide users with high quality products and accurate technical support.
