Housings For Electronic Packages
Aluminum Silicon(AlSi) alloys are binary alloys of silicon and aluminum, produced by our proprietary rapid solidification process. These controlled expansion Al-Si alloys are manufactured 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. The specific applications of these alloys in summarized in below Table. Aside from tailoring the CTE, the key advantages these alloys over materials such as kovar and CuW are reduced weight, high stiffness and ease of manufacture.
