5182 aluminum alloy is a non-heat treatment enhanced alloy, with magnesium atomic solid solution strengthening and grain refinement strengthening. After being placed at room temperature, it is easy to appear Lueders band during stretching, which leads to wrinkling of the surface after stamping forming and affects the appearance. Due to the non-heat treatment form of alloy, poor strength, baking will appear softening phenomenon, mostly used for automotive inner plate, because of the coating, corrosion resistance is good, the most used by the vehicle factory.

 

The 5182 aluminum plate is usually used for the four doors and two covers of automobiles, as well as the doors and the front and rear covers of automobiles. Among them, the role of the car hood can not be underestimated. The hood of the car reduces the noise of the engine, but also can isolate the heat generated when the engine is working, effectively protect the paint on the hood surface, prevent aging, can play a role in protecting the engine and the surrounding pipeline accessories. Under the hood are all the important parts of the car, including the engine, the circuit, the brake system and the transmission system, which are crucial to the vehicle. By improving the strength and structure of the hood, it can fully prevent impact, corrosion, rain and electrical interference and other adverse factors, and fully protect the normal work of the vehicle. The corrosion resistance of the 5182 aluminum plate determines the car hood "use it".
