20Mn23AlV
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.
