Silicon-aluminum alloy is a binary alloy composed of silicon and aluminum. It is an alloy material mainly used in aerospace, space technology and portable electronic devices. The silicon-aluminum alloy material can maintain the excellent properties of silicon and aluminum, and the content of silicon and aluminum is quite rich. The preparation technology of silicon powder is mature and the cost is low, and the material has no pollution to the environment and is harmless to the human body.
When the silicon content is low, the aluminum-silicon alloy has good ductility and is commonly used as a deformed alloy. When the silicon content is high, the aluminum-silicon alloy melt has good filling properties and is commonly used as a casting alloy. In the aluminum-silicon alloy with silicon content exceeding the Al-Si eutectic point, when the particle content of silicon is as high as 14.5% to 25%, adding a certain amount of Ni, CU, Mg and other elements can improve its comprehensive mechanical properties. They can be used in automotive engines to replace weight cast iron cylinders with significant weight savings. The aluminum-silicon alloy used as a cylinder can be electrochemically treated to etch the surface aluminum to retain the primary silicon dots embedded in the substrate on the inner wall of the cylinder, and the scratch resistance and wear resistance are remarkably improved. The alloy containing 11% to 13% of silicon is one of the best piston materials due to its light weight, low expansion coefficient and high corrosion resistance.
