★ Aerospace Aircraft wings, rocket shells, satellites, and spacecraft structural parts.
★ Other industries Power tools, bicycles, suitcases, torches, etc.
3. Compared with magnesium alloy die casting and aluminum alloy die casting:
★ 50% higher productivity.
★ Steel mold can be used to extend service life.
★ Lower latent heat, save energy.
★ Good machinability.
★ 50% savings in mold costs.
★ The melt has higher fluidity.
4. Types and applications of magnesium alloys:
◆ AZ91: It has good casting performance and strength, and is used for complex thin-walled parts, such as automobiles, computer parts, hand tools, sports equipment, and household appliances.
◆ AM50, AM60: It has outstanding toughness and energy absorption, and has good strength and mechanical properties. It is used for car seats, steering wheels, dashboards, wheel hubs.
◆ AM20: With high toughness and impact strength, it is used for parts that require high toughness.
◆ AS41: Good creep resistance at 150 degrees, used to withstand high load parts, such as cylinder block.
★ Good cutting performance.
★ Magnesium alloy has excellent appearance and touch texture, making the product more luxurious.
★ Recyclable and environmentally friendly.
★ The reserve of magnesium in the earth's crust ranks eighth. Most of the magnesium raw materials are extracted from seawater, so its resources are stable and sufficient.
