Baienwei company develops, manufactures and sells a wide range of controlled expansion Si/Al alloys which combine the advantageous of light weight,low expansion and high thermal conductivity features,such as the AlSi50(Al-50Si controlled expansion alloys) housings.
Main Benefits of controlled expansion Al-50Si alloy housings:
Baienwei's AlSi alloys
Silicon particles are refined and distribute well,any part of the alloy material is consistent with an average grain size of 10μm,shows uniform and isostropic.
Silicon particles distribute well,no stoma and holes,so improve the strength performance and product yield.
CTE(Coefficient of thermal expansion)
Silicon content occupes by the weight of 27%~80%,adjusted CTE in the range of 7~17ppm/℃ is available,CTE can be tailored based on client 's requirements.
Lower and Affordable cost
High-efficiency process routing,enhance product yield and reduce the cost.
Good machinability and platability.
Baienwei's Al-Si alloys ensure compact density can reach up to 100%,close tightness and have excellent welding performance.
Using standard aluminum eletroless plating,good plating adhesion strength.
Baienwei ensures relative density of alloys is 100%,good hermetic performance of chamber and keep the electronic components longevity
