Overview Beneficial Properties of High Silicon/aluminum(AlSi) Alloys
Dec 20, 2017

The key benefits of controlled expansion alloy(AlSi27~AlSi80):

●The controlable low thermal expansion coefficients(CTE) in the range of 7~17ppm/℃

●Ease of machined,controlled expansion alloy(AlSi) can be tailored to all sizes and shape 

●Common electroplating process,ease of soldering,such as arc welding,laser welding and electron beam welding process   

●Relative density which could be reach up to 100%.

●Possess lower weight and effective cost.

●The microstructure shows a uniform and isotropic,no porosity and holes 

●Higher strength and specific stiffness eminently suitable for a wide range of applications

●Excellent EMI/RFI shielding performance

●Environmentally friendly,present no disposal problems
