★The melt has a higher fluidity.

4. Types and applications of magnesium alloys:

◆ AZ91: With good casting performance and strength, it is used for complex-shaped thin-walled parts, such as automobiles, computer parts, hand tools, sports appliances, and household appliances.

◆ AM50, AM60: It has outstanding toughness and energy absorption, and has good strength and mechanical properties. It is used in car seats, steering wheels, dashboards, and car wheels.

AM20: High toughness and impact strength, used for parts requiring high toughness.

AS41: good creep resistance at 150 degrees, used to withstand high load parts, such as cylinder block.

★Good cutting performance.

★The appearance and touch texture of magnesium alloy is excellent, making the product more luxurious.

★Recyclable, green environmental protection.

★The reserves of magnesium in the earth's crust rank eighth, and most of the magnesium raw materials are extracted from seawater, so its resources are stable and sufficient.
