One of the uses of al-si alloy product

al-si alloy products can be used in automobile engines to replace cast iron cylinders and significantly reduce weight. The aluminum-silicon alloy used for the cylinder can be electrochemically treated to etch the surface aluminum and retain the primary silicon particles embedded in the matrix on the inner wall of the cylinder, and its scratch resistance and wear resistance are significantly improved. Among them, alloys with silicon content of 11% to 13% have become one of the best piston materials due to their light weight, low expansion coefficient and high corrosion resistance.

Advantages of al-si alloy products

Al-si alloy product has soft phase (Al) and hard phase silicon, which is a typical wear-resistant structure and has good wear resistance; the electronic potential of (Al) and eutectic silicon is not much different, and the surface is a layer of Al2O3, with a dense structure. It has a protective effect on the matrix, so it has good corrosion resistance; the eutectic temperature of ZL102 alloy is 577 ℃, which is higher than that of other cast aluminum alloys.

al-si alloy product | Introduction

Al-si alloy product is a very important industrial alloy, widely used in aviation, transportation, construction, automobile and other important industries, and also used to manufacture low and medium strength castings with complex shapes, such as cover plates, motor shells, Brackets, etc., are also used as brazing solders. The alloy is a typical alloy with a simple phase diagram and no intermediate compounds are produced. 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 very small.

Frequently Asked Question

Do you have any question?

Tianjin Zuoyuan New Material Technology Co., Ltd. is a high-tech company specializing in the research of advanced metal material preparation technology and the development, production and sales of high-performance metal materials. With the valuable experience accumulated over the years in the field of non-ferrous metal development and the integration of advanced automation control technology, Zhongyuan has achieved remarkable results in the field of high-performance metal materials and has become an innovative enterprise with strong competitiveness in this field. The superhard aluminum alloys and high wear-resistant aluminum alloys developed by the company have been successfully applied in high-end fields such as aerospace, satellite communications, and auto parts industries.

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.
