Application of aluminum profile in the automobile industry
Cast aluminum alloy has excellent Bai casting properties. The suitable alloy and casting method can be selected according to the requirements of using purpose, shape, size accuracy, quantity, quality standard, mechanical properties, and economic benefits. Casting aluminum alloy is mainly used for casting non-engine components such as engine cylinder block, clutch housing, rear axle housing, steering gear housing, transmission, valve distribution mechanism, oil pump, water pump, rocker cover, wheel, engine frame, brake caliper, oil cylinder, and brake disc.
The deformed aluminum alloy is mainly used in the manufacture of car body panels such as doors and suitcases, bumpers, engine covers, wheel spokes, wheel hub covers, wheel exterior trim covers, brake assembly protection covers, silencing covers, anti-lock brake system, heat exchanger, body frame, seats, car floor and other structural parts, as well as instrument panels and other decorative parts. Ai-six high silicon aluminum alloy replaces sintered steel to manufacture the rotor and blade of automobile air conditioning compressor in large quantities, which reduces the weight of the rotor by 60% and the weight of the whole compressor by 40%; the rapid solidification high silicon aluminum alloy piston produced by Yamaha automobile manufacturing company has also been put into the market. Compared with ordinary cast iron, the weight of the piston is reduced by 20%, the service life is increased by 30%, and the noise is significantly reduced, In order to reduce the pollution, Mazda Automobile Company made a new type of engine rotor by spray deposition of AI Si Fe Cu Mg alloy, which improved the engine efficiency and saved 20% oil.
Foam aluminum alloy is a porous material with numerous bubbles in the metal matrix. The material is lighter in weight and higher in weight to weight ratio and has higher energy absorption characteristics, higher damping properties, and vibration absorption characteristics. The sandwich panels made of foamed aluminum between two high strength outer panels can improve stiffness, lighten, and improve the insulation performance when used in the body top plate. When used in bumpers, longitudinal beams and some pillar parts, the ability to impact energy absorption can be increased, and the impact of safety can be improved while lightening.
