Low Cost AlSi42 Mirror For Satellite Component

Low Cost AlSi42 Mirror For Satellite Component
The AlSi42 alloy always been chosen as mirror for satellite application.
Product Details

AlSi42 alloy has been widely used for mirror in the satellite application.

Compared with other material,the AlSi42 alloy is lower weight,it is almost 1/4 the weight of copper.As the benefits of adjustable coefficient of thermal expansion,higher thermal conductivity,low density and ease of machinability,the AlSi42 alloy is suitable for mirrors.
