Aluminum Silicon Alloy Powderis a binary alloy composed of silicon and aluminum, and is a metal-based thermal management material. High- Aluminum Silicon alloy Powder materials can maintain the excellent properties of aluminum and silicon, and the content of aluminum and silicon is quite abundant.
Why add silicon to aluminum?
The silicon powder preparation technology 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.
When it is added to aluminum, silicon makes the metal alloy more fluid without damaging the metal at high temperatures. Silicon actually lowers the melting point of aluminum. Aluminum does not experience hot tearing because there is no brittleness.
Properties of Aluminum Silicon Alloy Powder
The density of high Aluminum Silicon 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, Aluminum Silicon alloy also has good thermal conductivity, high specific strength and rigidity, good electroplating performance with gold, silver, copper, and nickel, can be welded with the substrate, and easy to precision processing. It is a kind of Electronic packaging materials with broad application prospects, especially in high-tech fields such as aerospace, space technology, and portable electronic equipment.
