Baienwei Co.,Ltd produces a series of controlled expansion alloys(Si content:27%~70%) which particularly applied in space and aerospace industries.The Al-70%Si alloy has been widely used in carrier for telecommunications.In contract to original Kovar alloy,it has less than 1/3 the weight,7x thermal conductivity and similar low thermal coefficients.Moreover,Al-27%Si alloy offer a lower CTE,improve stiffness and rigidity and stays flat.Please see the Si/Al alloys overall features:
The key benefits of controlled expansion alloys:
●The controlable low thermal expansion coefficients(CTE) in the range of 7~17ppm/℃
●Ease of machined,controlled expansion alloys(AlSi alloy) 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 uniform and isotropic,no porosity and holes
●Higher strength and specific stiffness distinctly in a wide range of applications
●Excellent EMI/RFI shielding performance
●Environmentally friendly,present no disposal problems
Providing with carrier for telecommunications free sample, BAIENWEI is one of the competitive carrier for telecommunications manufacturers and suppliers. Welcome to import customized products in stock from our factory.
