Silicon Alumium Alloy Powder Properties
Introduction of Silicon Aluminum Alloy Si-Al Powder:
High-silicon aluminum alloy powder is a binary alloy composed of silicon and aluminum, and is a metal-based thermal management material. The high-silicon aluminum alloy material can maintain the excellent performance 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 high-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. At the same time, high-silicon aluminum alloy also has good thermal conductivity, high specific strength and stiffness, good plating performance with gold, silver, copper, nickel, weldable with the substrate, easy precision machining and other superior performance, is a Electronic packaging materials with broad application prospects, especially in high-tech fields such as aerospace, space technology, and portable electronic devices.

Application of Silicon Aluminum Alloy Si-Al Powder:
1) High-power integrated circuit packaging: high-silicon aluminum alloy provides effective heat dissipation;
2) Carrier: It can be used as a local heat sink to make the components more closely arranged;
3) Optical frame: high-silicon aluminum alloy provides low thermal expansion coefficient, high rigidity and machinability;
4) Heat sink parts: high silicon aluminum alloy provides effective heat dissipation and structural support.

Application of Silicon Aluminum Alloy Si-Al Powder in auto parts:
High-silicon aluminum alloy material (with silicon content of 20%-35%) has excellent tribological properties, and can be used as an advanced lightweight wear-resistant material in various transportation vehicles and various types of power machinery, machine tools, special fasteners And tools have been widely used.
High-silicon aluminum alloy has a series of advantages such as small specific weight, light weight, good thermal conductivity, low thermal expansion coefficient, volume stability, good wear resistance, good corrosion resistance, etc., and is widely used as cylinder sleeves, pistons, rotors of automobile engines , Brake discs and other materials.

Storage Condition of Silicon Aluminum Alloy Si-Al Powder:
Damp reunion will affect Si-Al powder dispersion performance and using effects, therefore, silicon aluminum alloy powder should be sealed in vacuum packing and stored in cool and dry room, the silicon aluminum alloy can not be exposure to air. In addition, the silicon aluminum alloy powder should be avoided under stress.
