Product Details
2J83, 2J84, 2J85 Wrought Iron-Chromium-Cobalt Permenent Magnet
Alloys
Iron-chromium-cobalt permanent magnet alloy not only has good
ductility, but also has good magnetic properties. It is the most
widely used deformable permanent magnet material at present. Its
magnetic properties are comparable to cast aluminum nickel cobalt
alloy, and the price is cheaper than iron cobalt vanadium permanent
magnet alloy. The alloy is characterized by homogeneous
composition, compact structure and stable performance. It can
replace some cast Al-Ni-Co alloys and Fe-Co-V alloys to make
complex permanent magnet components.

Characters
- Heat resistant: magnetism does not decline below 400 degrees
- Can be machined, such as cutting, tapping, drilling, stamping, etc.
- Impact resistance while other magnetic materials are fragile and
easy to crack.
- Magnetic requirements can be adjusted according to customer needs
(semi hard magnetic properties can be made).
- Good corrosion resistance
