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
