Introduction to Silicon Aluminum Alloy

Introduction to Silicon Aluminum Alloy

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. At the same time, silicon-aluminum alloy also has good thermal conductivity, high specific strength and rigidity, good plating performance with gold, silver, copper, nickel, weldability with substrates, easy precision machining, etc. It is a kind of superior performance. Electronic packaging materials with broad application prospects, especially in high-tech fields such as aerospace, space technology and portable electronic devices.

According to the processing method, aluminum alloys can be divided into two categories: deformed aluminum alloys and cast aluminum alloys.

Deformed aluminum alloys can withstand pressure processing. It can be processed into aluminum alloys of various shapes and specifications. Mainly used in the manufacture of aviation equipment, doors and windows for construction, etc. Deformed aluminum alloys are further divided into non-heat-treatable-strengthened aluminum alloys and heat-treatable-strengthened aluminum alloys. The non-heat-treatable-enhanced 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 through heat treatment methods such as quenching and aging. They can be divided into hard aluminum, forged aluminum, super-hard aluminum, and special aluminum alloys. Cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys and aluminum-rare-earth alloys according to their chemical composition. Crystal silicon aluminum alloy and cast aluminum alloy are used in the as-cast state.

The use of silicon aluminum alloy

The content of the deoxidizer is different, and the products are also different, such as silicon aluminum iron, silicon calcium manganese, etc. The following are the uses of silicon aluminum alloy:
Application of deoxidizer in steelmaking: In order to obtain lower oxygen content, it is necessary to add ferrosilicon during the tapping process to generate deoxidation products, most of which can be excluded from molten steel;
Application of slag remover in steelmaking: adding ferrosilicon in steelmaking can collect oxides on the surface of molten steel, making it easier to collect and filter impurities and improve the purity of steel;
Application of aluminum element in ferrosilicon: adding a small amount of aluminum element to steel can refine grains, improve impact toughness, corrosion resistance of aluminum element in ferrosilicon, aluminum, chromium and silicon are used together, It can improve the high temperature non-skinning performance and high temperature corrosion resistance of steel.

The main purpose of aluminum alloy

Aluminum alloys are made of pure aluminum and some alloying elements, such as aluminum-manganese alloys, aluminum-copper alloys, aluminum-copper-magnesium hard aluminum alloys, and aluminum-zinc-magnesium-copper superhard aluminum alloys. Aluminum alloy has better physical and mechanical properties than pure aluminum: easy processing, high durability, wide application range, good decorative effect, and rich colors. Aluminum alloys are divided into anti-rust aluminum, hard aluminum, super hard aluminum and other types, each type has its own scope of use, and has its own code for users to choose.
Aluminum alloy still maintains the characteristics of light weight, but the mechanical properties are significantly improved. The application of aluminum alloy materials has the following three aspects: one is as a force-bearing member; the other is as a material such as doors, windows, pipes, covers, and shells; the third is as a decorative and thermal insulation material. Using the characteristics of aluminum alloy that can be colored after anodizing treatment, it can be made into various decorations. The surface of aluminum alloy sheets and profiles can be processed by secondary processing such as anti-corrosion, embossing, painting, printing, etc., and can be made into various decorative sheets and profiles as decorative materials.

Frequently Asked Question

Do you have any question?

Yes. All AlSi alloys can be machined easily, such as CNC, EDM, wire cutting etc.

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.
