Application of Mingtai Aluminum aluminum alloy plate in auto

Aluminum is a silvery white metal with a relative density of 2.7. The melting point is 657 ° C, while the relative density of iron is 7.8 and the melting point is 1535 ° C. In addition to magnesium and barium in practical metals, aluminum is the lightest. Its purity can be as high as 99.99%. Usually it is 98.0%-99.7%. Aluminum is soft and has low strength in the pure metal state, so it is not suitable for use as a structural material alone. However, after alloying with other metals, it is easy to process at normal temperature or high temperature, and relatively excellent mechanical properties can be obtained. This alloy is called a light alloy.
The use of aluminum sheeting in a car is limited to the use of body parts that do not have a significant impact on strength. For example, the door, engine cover, trunk cover and other body gold-plated parts.
Others can also be applied to external parts, the surface of which requires a shiny portion of the metal. For example, it is used in trim strips, water tank front trims, side bumpers, and the like. When aluminum sheet is used, in order to prevent oxidative corrosion and lose luster, the aluminum sheet product is anodized after completion, and a 0.033 mm thick alumina sheet film is formed on the surface to achieve corrosion resistance, and the surface thereof is also Can be repainted.
The plate-shaped 5052 aluminum plate or foundry can also be welded. However, it is necessary to remove the anodized aluminum plate of the weld and use the aluminum flux for welding.
