[0002] Magnesium alloy is an alloy composed of magnesium as the base and other elements added. Its characteristics are low density, high strength, large elastic modulus, good heat dissipation, good shock absorption, greater ability to withstand impact loads than aluminum alloy, and good corrosion resistance to organic substances and alkalis. Before processing magnesium alloy die-castings, certain surface treatments are required. When performing surface treatment on magnesium alloy castings, dust and waste chips will be generated, polluting the environment and endangering the physical health of workers.
