Aluminum alloy for wheel hub
Aluminum wheels have gradually replaced steel wheels because of their light weight, good heat dissipation and good appearance. In the past 10 years, the global aluminum alloy automobile wheels have grown at an annual growth rate of 7.6%, and the aluminization rate of automobile wheels can reach 72% to 78%. Silicon-aluminum alloy, which has good casting properties and high comprehensive mechanical properties, is an example of the application of aluminum alloys in automobiles, and almost all new models use aluminum alloy wheels.
The development prospect of silicon aluminum alloy in automobile
Among lightweight metals, although the density of magnesium alloys is lower than that of silicon-aluminum alloys, the cost of magnesium ingots is higher, and there are many technical obstacles in the manufacturing process of parts, such as lack of high-temperature die-casting alloys and design data, poor surface treatment technology, and poor bonding level. Low-grade, so the current use in automobiles is quite limited; and although titanium alloys for aerospace have high mechanical strength, the manufacturing process is difficult and the manufacturing cost is expensive, resulting in the inability of titanium alloys to be applied to automobile production in large quantities. Aluminum alloy has good comprehensive performance in terms of cost, manufacturing technology, mechanical properties, sustainable development (the most aluminum content in the earth's crust, accounting for 8.1%), etc. Therefore, aluminum-silicon alloy is the preferred light metal material in the automotive industry now and in the future.
Silicon aluminum alloy for engine
Aluminum alloys for automobile engines are the most lightweight, generally reducing weight by more than 30%. In addition, both the cylinder block and the cylinder head of the engine require materials with good thermal conductivity and strong corrosion resistance, and aluminum alloys are very prominent in these aspects. Therefore, various automobile manufacturers have carried out the research and development of the aluminum alloy of the engine.

We have a rapid solidification process, which is further optimized on the basis of the spray molding process (also known as spray deposition), which is similar to the atomization pulverization process, which sprays molten, atomized metal onto a rotating substrate , the metal forming process of forming metal ingots or billets. . This process has a high solidification rate and a relative density of over 99.2%. After hot working (forging, rolling, extrusion or HIP), the material is processed into a dense product.
Yes. All AlSi alloys can be machined easily, such as CNC, EDM, wire cutting etc.
