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

Magnetic properties

Grade	Type	B_r/T	H_c(kA/m)	(B·H)_max/(kJ/m³)
2J83	anisotropy	1.05 min	48 min	24~32
2J84	anisotropy	1.20 min	52 min	32~40
