Product Description

Iron-Cobalt Permenent Magnetic Alloy 2J4


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 time application and a large dosage.


After the years of exploration and practice, the technology and production process of the Magnetic Alloy 2J4,2J9,2J10 series products have been more improved, We have deep research and rich experience in alloy 2J4, 2J9, 2J10 products ,so we can provide high-quality products and precise technical support.


It is similar to Vicalloy-2J10 in China standard.
