Electro-optical Housing

Electro-optical Housing

Baienwei'company produces a family of binary AlSi alloys products,and the alloy products are finding increasing use in the electronics industry for a wide range of applications.These lightweight alloys are composed of silicon-aluminum and by adjusting the proportions of these two constituents the coefficient of thermal expansion (CTE) can be controlled to any pre-selected value between 7 and 17 ppm/°C. For example,the AlSi70 alloy eletro-optical housings.

Product Details

Thermal management products possess the light weight-lower CTE-high thermal conductivity features,such as the Si-30wt.%Al(AlSi70) alloy electro-optical housings.


Main attributes of Si-30Al Controlled Expansion alloy(AlSi70) alloy:

●Low CTE anCTE match to components, and stable with temperature;

●High thermal conductivity;

High stiffness;

Good hermeticity;

Manufacturability (ease of machining and plating).
