Aluminum-silicon alloy Aluminum-silicon alloy, also known as "high-silicon aluminum alloy", is mainly a binary alloy material composed of two elements, aluminum and silicon. Aluminum-silicon alloy is a new type of composite material, which has high thermal conductivity and good strength, and can be seen in many industrial fields. Aluminum-silicon alloy materials can be divided into 27, 40 and other grades because of the different proportions of components contained in them. At present, it has many applications in the fields of electronic packaging and aerospace. Aluminum-silicon alloys and aluminum-based silicon carbide have many similarities, and in terms of processing difficulty, aluminum-silicon alloys are easier to process.
The plasticity of aluminum is large, and a large amount of work is consumed during cutting. With the increase of silicon content, the eutectic increases and the cutting work can be reduced. However, the hardness of eutectic silicon is high, and it is easy to wear the tool, especially the excessive co-crystallization of coarse primary silicon. crystalline alloy, the tool wear is more serious, and the machined surface is very rough. In order to improve the cutting performance, in addition to the corresponding modification treatment to refine eutectic silicon and primary silicon, free cutting elements such as bismuth and lead can be added; for hypereutectic alloys, diamond-inlaid tools can be used to select the best cutting speed. And suitable cutting fluid, etc., can also obtain a smooth surface.
Aluminum-silicon alloy aluminum alloy can be divided into deformed aluminum alloy and cast aluminum alloy according to the processing method. Deformed aluminum alloys are divided into non-heat-treatable-strengthened aluminum alloys and heat-treatable-strengthened aluminum alloys. The non-heat-treatable strengthening type cannot improve mechanical properties through heat treatment, but can only be strengthened through cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and rust-proof aluminum. Heat-treatable-strengthened aluminum alloys can improve their mechanical properties by means of heat treatment such as quenching and aging. They can be divided into hard aluminum, forged aluminum, super-hard aluminum, and special aluminum alloys.

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.
