5182 aluminum alloy is a non heat treated strengthening alloy that has magnesium atom solid solution strengthening and grain refinement strengthening. After being placed at room temperature, it is prone to the appearance of Luedes bands during stretching, leading to surface wrinkling after stamping and affecting the appearance. Due to its non heat treated shape and poor strength, it tends to soften during baking and is commonly used for automotive interior panels. Due to its excellent coating and corrosion resistance, it is widely used by vehicle manufacturers.
5182 aluminum plate is usually used for the four doors and two covers of automobiles, as well as the doors and front and rear covers of automobiles. Among them, the role of car engine covers cannot be underestimated. The car hood not only reduces engine noise, but also isolates the heat generated during engine operation, effectively protecting the paint surface on the hood and preventing aging. It can also protect the engine and surrounding pipeline accessories. Under the hood, it is an important component of a car, including the engine, circuit, braking system, and transmission system, which are crucial to the vehicle. By improving the strength and structure of the hood, adverse factors such as impact, corrosion, rainwater, and electrical interference can be fully prevented, fully protecting the normal operation of the vehicle. The corrosion resistance of 5182 aluminum plate determines that the car hood is not used.
