We apply the silicon aluminum alloys (Controlled expansion AlSi alloy) which can be widely used in various high-end fields, for example the electronic packaging,structural products(e.g.lens holder),machinery & heavy industries etc.Tianjin Baienwei New Material Technology Co.,Ltd has passed the ISO9001:2008 Quality Management System.

The main attributes of Controlled expansion alloy(AlSi27~AlSi80):

1. The controllable low thermal expansion coefficients(CTE) in the range of 7~17ppm/℃;

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

3. Common electroplating process,ease of soldering,such as arc welding,laser welding and electron beam welding process;

4. Relative density which could be reach up to 100%;

5. Possess lower weight and cost effective;

6. The microstructure shows uniform and isotropic,no porosity and holes;

7. Higher strength and specific stiffness eminently suitable for a wide range of applications;

8. Excellent EMI/RFI shielding performance;

9. Environmentally friendly,present no disposal problems.
