Product advantages

1. Good electromagnetic shielding performance: The shells of 3C products (mobile phones and computers) must be able to provide superior anti-electromagnetic protection, while the magnesium alloy shell can completely absorb electromagnetic interference with frequencies exceeding 100db.
2. Good heat dissipation: The thermal conductivity of general metals is hundreds of times that of plastics. The thermal conductivity of magnesium alloys is slightly lower than that of aluminum alloys and copper alloys, and much higher than that of titanium alloys. The specific heat is close to water, which is the highest among commonly used alloys. By.
3. Good recyclability: As long as the cost is equivalent to 4% of the price of new materials, magnesium alloy products and waste materials can be recycled.
4. Stable resource provision: The reserves of magnesium in the earth’s crust rank eighth. Most of the magnesium raw materials are extracted from seawater, so its resources are stable and sufficient.
5. Light weight: The specific gravity of magnesium alloy is the lightest among all structural alloys. Its specific gravity is 68% of aluminum alloy, 27% of zinc alloy, and 23% of steel. In addition to the shell and internal structure of 3C products Besides parts, it is also an excellent material for parts such as automobiles and airplanes.
6. High specific strength and specific stiffness: The specific strength of magnesium alloy is significantly higher than that of aluminum alloy and steel, and the specific stiffness is equivalent to that of aluminum alloy and steel, but much higher than engineering plastics, which is 10 times that of general plastics.
7. Good vibration resistance: Under the same load, the vibration damping performance is 100 times that of aluminum and 300 to 500 times that of titanium alloy.
