Silicon Aluminum Alloy Particles SiAI Pellet / Ingot Evaporation Material

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. 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, low cost, and this material has no pollution to the environment and is harmless to the human body. The density of silicon aluminum alloy is between 2.4~2.7g/cm°, and the coefficient of thermal expansion (CTE) is between 7-20ppm/℃. Increasing the silicon content can significantly reduce the density and coefficient of thermal expansion of the alloy material.

At the same time, silicon aluminum alloy also has good thermal conductivity, higher strength and stiffness, good plating performance with gold, silver, copper, nickel, welding with the substrate, easy precision machining and other superior properties, is a broad application prospect of electronic packaging materials, especially in aerospace, space technology and portable electronic devices and other high-tech fields.

Silicon aluminum alloy is a composite strong deoxidizer, the density of silicon aluminum alloy is higher than that of pure aluminum, it is easier to enter the molten steel, and the internal burning loss is less. In the process of steel training, the use of silicon aluminum alloy, and then in the utilization rate than pure aluminum alone is many times higher, with silicon aluminum alloy deoxidation to form a low melting point of the product, can improve the quality of steel.
