Non-magnetic alloys are carbide materials that are not magnetic or weakly magnetic. As the moulds for the production of magnetic materials require the use of non-magnetic materials, non-magnetic steel has been used in the past, which has poor mould performance, low hardness, short service life, and after a period of time, the inner wall of the mould is severely stretched and deformed, which affects the dimensional accuracy and surface quality of magnetic materials. Nowadays, the use of non-magnetic carbide, with its excellent performance instead of non-magnetic steel can increase the efficiency exponentially.
