Tianjin Zuoyuan New Material Technology Co., Ltd. is a high-tech company specializing in advanced metal material preparation technology research and high-performance metal material development, production and sales. Mainly produces high-silicon aluminum alloy and superhard aluminum alloy, including alloy raw materials, bars, pipes, plates, profiles and so on. Widely used in aerospace, aviation, electronics, automotive, machinery and petroleum industry and other sophisticated fields.
High-silicon aluminum alloy is a binary alloy composed of silicon and aluminum, which is a metal-based thermal management material. High silicon aluminum alloy material can maintain the excellent properties of silicon and aluminum, and the content of silicon and aluminum is quite rich. The density of high-silicon aluminum alloy is between 2.4 and 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. At the same time, high 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 promising electronic packaging material, especially in high-tech fields such as aerospace, space technology and portable electronic devices.
The preparation methods of high silicon aluminum alloy composite materials mainly include the following: 1. Smelting and casting; 2. Infiltration method; 3. Powder metallurgy; 4. Vacuum hot pressing method; 5. Rapid cooling/spray deposition method.
Aluminum-silicon alloys have the following uses:
1. In aluminum-silicon alloys whose silicon content exceeds the Al-Si eutectic point (silicon 11.7%), silicon particles can significantly improve the wear resistance of the alloy, forming a class of wear-resistant alloys with a wide range of uses.
2. It is used to manufacture low and medium strength castings with complex shapes, such as cover plates, motor casings, brackets, etc., and is also used as brazing solder.
3. Aluminum-silicon alloy is a kind of strong composite deoxidizer. It can improve the utilization rate of deoxidizer by replacing pure aluminum in the steelmaking process, and can purify molten steel and improve the quality of steel. Ingots deoxidized with aluminum are generally called stabilized steels. Since aluminum is deoxidized and oxidized into alumina, alumina can refine austenite grains, so aluminum deoxidized steels have better comprehensive mechanical properties.
4. Silicon aluminum alloy has low density, low thermal expansion coefficient, good casting performance and anti-wear performance. The alloy castings cast with it have high impact resistance and good high pressure compactness, which can greatly improve the service life. Spacecraft and auto parts.
In the steelmaking process, both aluminum and ferrosilicon are strong deoxidizers, but aluminum has a low density, low melting point, and is easy to oxidize. Due to its high density and high melting point, ferro-aluminum is easy to sink into molten steel, so its utilization rate can reach 70%. The traditional method of smelting ferrosilicon and aluminum is obtained by melting ferrosilicon and aluminum, which consumes a large amount of aluminum and has high cost. The submerged arc furnace method uses bauxite as the main raw material, which has wide resources and low price, and has broad development prospects.
