Si-aluminum alloys are of great significance to reduce environmental pollution through energy saving. In the field of automotive materials, in addition to relying on parts thinning, hollowing and miniaturization to save energy, the main method is the lightweighting of materials, so the research on lightweight materials is currently one of the most active research directions in the field of automotive materials in the world. one. At present, the lightweight materials mainly use various high-strength steels, which can reduce the weight of automobiles by 15%-20%.
Silicon-aluminum alloy cylinder liner can improve fuel economy, excellent anti-vibration, noise reduction and damping characteristics, and high thermal conductivity. Si-aluminum alloy cylinder liners are lighter in weight. Due to the low density of silicon-aluminum alloy, in the automotive industry, 1 kg of silicon-aluminum alloy can replace 3 kg of cast iron. The silicon-aluminum alloy cylinder liner greatly improves the power of the engine, making its comprehensive performance higher, and the output power can be increased by at least 15%. Silicon aluminum alloy cylinder liner has good tribological properties. The silicon particles in the silicon-aluminum alloy have wear-resistant and self-lubricating effects.
The silicon-aluminum alloy cylinder liner material has good compatibility with the thermophysical properties of the piston aluminum alloy material, and can realize "gapless cylinder matching" and "all-aluminum engine". It is beneficial to reduce the risk of thermal erosion failure of piston "burning top" and the risk of "pulling cylinder" and "biting" failure. It has become the main material of new engine cylinder liners.

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.
