A brief description of silicon aluminum alloy

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. At the same time, this material does not pollute the environment and is harmless to the human body. The density of silicon aluminum alloy is between 2.4~2.7 g/cm³, and the coefficient of thermal expansion (CTE) is between 7-20ppm/℃. Increasing the silicon content can significantly reduce the density and thermal expansion coefficient of the alloy material.

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.
