Si25Al30 Alloy Agent In Steel Industrial Alloys For Aviation And Transportation​

Introduction:

     Al-Si alloy is an important industrial alloy widely used in important industries such as aviation, transportation, construction, automobile, etc. It is also used to manufacture low-medium-strength and complex-shaped castings such as cover plates, motor casings, and supports. Brass, etc., also used as brazing solder. The alloy is a typical eutectic alloy with a simple phase diagram and no intermediate compounds. It has the advantages of good casting performance, high specific strength and low price. Aluminum is the third main group element, and silicon is a semiconductor element, and the solid solubility between the two is small.

Performance and use:

     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 an aluminum-silicon alloy containing more than the Al-Si eutectic point (silicon content of 12.6%), when the particle content of silicon is as high as 14.5% to 25%, a certain amount of Ni, CU, Mg, etc. can be improved. 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.
