What is the application of aluminum alloy?


Casting aluminum alloy has the highest density and excellent casting performance, according to the purpose of use, parts shape, dimensional accuracy, quantity, quality standards, mechanical properties and other aspects of the requirements and economic benefits to choose the appropriate alloy and the appropriate casting method, made of complex shape parts. Cast aluminum alloy is mainly used for casting engine cylinder body, clutch housing, rear axle housing, steering gear housing, transmission, valve mechanism, oil pump, water pump, rocker cover, wheels, engine frame, brake calipers, oil cylinder and brake disc and other non-engine components.


Engine with aluminum alloy cast iron engine is gradually replaced by aluminum alloy, mainly because the engine with aluminum alloy manufacturing light weight is obvious, generally can be reduced by more than 30*, aluminum alloy has strong heat dissipation, good thermal conductivity, corrosion resistance is very prominent advantages, so the automobile manufacturers have carried out engine aluminum research and development. At present, many foreign automobiles have adopted all-aluminum engine cylinder block and cylinder head.


The aluminum alloy wheel hub is used as the inner rim of the tire to support the cylindrical, central assembly on the shaft of the parts, the material strength requirements are high, and the aluminum alloy is not only high strength, and the density is small (about 1/3 of the steel), which means that the same volume of aluminum alloy wheels will be lighter than steel wheels 2/3, is one of the important ways to achieve automotive lightweight. Aluminum wheels have gradually replaced steel wheels because of their light weight, good heat dissipation and good appearance.


The application of deformed aluminum alloy through stamping, bending, rolling, extrusion and other processes to make its organization, shape of the aluminum alloy become deformed aluminum alloy, generally through the melting process, and then subjected to metal plastic deformation processing. Deformed aluminum alloy in the automobile is mainly used in the manufacture of doors, suitcases and other body panels, bumpers, engine covers, wheel spokes, hubcaps, wheel exterior cover, brake assembly protective cover, muffler cover, anti-lock braking system, heat exchangers, body frames, seats, chassis bottom and other structural parts and instrument panels and other decorative parts.


At present, cold stamping is still the main process of mass forming aluminum alloy body structural parts and covering parts. The application proportion of plates in cars is increasing, such as heat treatment


It is believed that with the optimization of aluminum alloy materials in the near future, its performance will be greatly improved, and the application will be extended to more new fields.
