Product Details

Aluminum Silicon alloys are binary alloys of silicon and aluminum, produced by our proprietary rapid solidified process. These controlled expansion Al-Si alloys are provided in a range of weight proportions of silicon and aluminum from 70Si/30Al to 27Si/73Al, with CTE’s 7 to 17 ppm/°C respectively. Aluminum Silicon(AlSi) alloys are lightweight, high thermal conductivity alloys that are increasingly being used for RF & microwave packages, electro-optical housing, power device base plates and other critical heat sinking applications.
