45Mn17Al3 low magnet-based single-phase high-alloy austenitic manganese steel. With good ductility, toughness, work hardening tendency of large, thermal expansion coefficient, specific resistance, low thermal conductivity and low magnetic physical properties. In the non-magnetic construction, non-magnetic machinery, mineral prospecting equipment and military and other fields have a wide range of applications.

No magnets are now widely used in many electrical products:
A medium-sized transformer tank inside a magnetic shield, core pull plate, coil clamps, bolts and other structural parts of the leakage magnetic field;
Second, lifting magnet sucker, magnetic separation equipment Simplified, the election boxes and separator;
Three Special smelting furnace lining, lid, plywood and electronic mixing device electrode structure.
