Under the urgent situation that the world automobile industry pays more and more attention to energy conservation and environmental protection, the three major issues of energy saving, environmental protection and safety improvement are urgent problems that the automobile industry urgently needs to solve. Because the forming, production performance and steel plate of aluminum plate are very close, the use of aluminum alloy instead of steel materials is one of the main means for automobile manufacturers in various countries to reduce the weight of automobiles. Today, KK Aluminum will take you to know the commonly used 5182 automotive aluminum plate.
5182 aluminum alloy is a non-heat treatment strengthening alloy, with magnesium atom solid solution strengthening and grain refinement strengthening, after room temperature placement, it is easy to appear Lüders band when stretching, resulting in surface wrinkling after stamping and forming, affecting the appearance. Because it is a non-heat treatment alloy, the strength is poor, and there will be softening phenomenon when baking, which is mostly used in automotive interior panels, and is used by automakers the most because of its coating and good corrosion resistance.
5182 aluminum plate is usually used for four doors and two covers of automobiles, as well as doors, front and rear covers of automobiles. Among them, the role of the car hood should not be underestimated. While reducing engine noise, the car hood can also isolate the heat generated by the engine during operation, effectively protect the paint surface on the hood surface, prevent aging, and protect the engine and surrounding pipeline fittings. Under the hood, are important parts of the car, including the engine, circuit, brake system and transmission system, etc., which are very important to the vehicle. By improving the strength and structure of the hood, it can fully prevent adverse factors such as shock, corrosion, rain and electrical interference, and fully protect the normal operation of the vehicle. The corrosion resistance of 5182 aluminum plate determines that the car hood is "not used".
Globally, the application of aluminum alloy technology in the body has always been at the forefront, the engine cover, fenders, doors, rear cover and other important parts of the car are made of aluminum alloy, and there is a gradual increase in the trend, domestic automobile manufacturers have also begun to use aluminum alloy covers and aluminum alloy skin. Looking to the future, the prospects of automotive aluminum are immeasurable.
