Fecrco Permanent Magnet Alloy Mechanical Workability Hot Rolled Bar Auto Ammeter
Fe-Cr-Co Permanent Magnet Alloy with Good Mechanical Workability
2J85 is a new type of permanent magnet. The properties of 2J85 are comparable to those of cast Al-Ni-Co magnets while it has a good ductility in the as-quenched state.
2J85 is specially suitable for making small and thin elements with accurated dimensions and complicated shapes.
Specification: YB/T 5261-2016 Wrought Iron-Chromium-Cobalt Permanent Magnet Alloys
