What are the applications of aluminum alloy?
Application of cast aluminum alloy Cast aluminum alloy has the highest density and excellent casting performance. According to the purpose of use, part shape, dimensional accuracy, quantity, quality standards, mechanical properties and other requirements and economic benefits, suitable alloys and suitable alloys can be selected. Casting method to make parts with complex shapes. Cast aluminum alloy is mainly used for casting engine cylinder block, clutch housing, rear axle housing, steering gear housing, transmission, valve train, oil pump, water pump, rocker cover, wheel, engine frame, brake caliper, cylinder and Non-engine components such as brake discs.
Aluminum alloy cast iron engines for engines are gradually being replaced by aluminum alloys. This is mainly due to the fact that the engine is made of aluminum alloy which is lighter in weight*, and generally can reduce weight by more than 30*. Aluminum alloy has strong heat dissipation, good thermal conductivity, and excellent corrosion resistance. Outstanding advantages, so all automobile manufacturers have carried out research and development of engine aluminum. At present, many foreign automobiles have adopted all-aluminum engine cylinder blocks and cylinder heads.
The aluminum alloy wheel hub used as the tire inner profile to support the tire is a cylindrical, middle*, and assembled component on the shaft. It requires high material strength. Aluminum alloy not only has high strength, but also has low density (about 1% of steel). /3), which means that the use of aluminum alloy wheels with the same volume will be 2/3 lighter than steel wheels, which is one of the important ways to achieve lightweight cars. Aluminum wheels are gradually replacing steel wheels because of their light weight, good heat dissipation, and good appearance.
The application of wrought aluminum alloy makes the structure and shape of the aluminum alloy changed by stamping, bending, rolling, extrusion and other processes to become wrought aluminum alloy. Generally, the ingot is made by the melting method and then subjected to metal plastic deformation processing. Deformed aluminum alloys are mainly used in the manufacture of car doors, trunks and other body panels, bumpers, engine hoods, wheel spokes, hubcaps, wheel exterior covers, protective covers for brake assemblies, muffler covers, and anti-lock brakes. Structural parts such as brake system, heat exchanger, body frame, seat, chassis floor, and decorative parts such as dashboard.
Aluminum alloy for body panels currently cold stamping is still the main process for mass forming of aluminum alloy body structures and covers. The application proportion of plates in cars continues to rise, 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 also be extended to more new areas.
