Corrosion Resist Magnesium Alloy Sheet High Temperature Aircraft , Engines , Missiles

Feature

• Low density (about 1.8g/cm3 magnesium alloy),
• high strength, large elastic modulus
• good heat dissipation, good shock absorption
• greater impact load bearing capacity than aluminum alloy
• good corrosion resistance to organic and alkaline properties

Advantages

Pure magnesium is not suitable as structural material, but magnesium alloy with alloying element has high strength and can be used as structural material. Magnesium alloys have the following advantages as structural materials:

1. light weight. Magnesium alloy, as a lightweight metal structure material, has a density of 1.74 cm-3, which is equivalent to 2/3 of that of aluminum, l/4 of steel and 1/4 of that of zinc. This feature is important for modern portable products to reduce weight and reduce vehicle energy consumption.

2. higher than intensity. Under the same rigidity condition, the strength of 1kg magnesium alloy is equal to 18kg aluminum and 2.1kg steel.

3. high shock absorption performance. Magnesium has excellent hysteretic and shock absorbing properties, can absorb vibration and noise.

4. good casting performance. Under the condition of maintaining good structure, the wall thickness of magnesium products can be less than 0.6mm, which cannot be achieved by plastic products under the same strength.

5. high die casting productivity. Magnesium alloys have a lower heat capacity than aluminum, which means they solidify faster in the mold.

Application

Development

1) The annual growth rate of global magnesium alloy demand is about 10%, and the market growth rate of Western magnesium alloy is more than 15%.

2) In the future, the market demand of magnesium alloy will show a rapid growth trend. Magnesium alloy is mainly used in automobile, 3C and aerospace fields, among which, it is used in automobile industry (70%), 3C industry (20%), military and aerospace industry (10%).

3) Specifically, the application of magnesium alloy in 3C industry (computer, communication, consumer electronics), electric tools, sports equipment, etc. has become a new market hotspot, such as notebook computer, handheld computer shell, camera shell, camera shell, projection video camera shell, television, sound shell, etc., and its application field is expanding rapidly.
