2J4 Iron Cobalt Hysteresis Permanent Magnet Alloy Corrosion Resistance

2J4 Iron-Cobalt Hysteresis Permanent Magnet Alloy Corrosion resistance

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.

2J4 belongs to Iron-Cobalt Permenent Magnetic Alloy,this alloy is suitable for making high efficiency hysteresis motor rotor with high operating temperature, and this alloy does not cause reduced magnetic performance in the range of + 150~ -140 ℃. In all kinds of the Magnetic Alloys, 2J4 is the one with a long application time and a large dosage. We can supply cold rolled strip of 2J4 alloy with mature process and stable quality in thickness range 0.05-1.0mm.
