Product Details

Tianjin Baienwei(BEW) company manufactures a wide range of Al-Si controlled expansion alloy products which possess the lightweight-low expansion-high thermal conductivity features,such as the microwave amplifier for satellite applications.


Tianjin Baienwei New Material Technology Co.,Ltd offers a family of lightweight, controlled expansion, Si/Al alloys in the form of machined carriers and housings. Typical uses include high performance devices, circuit and system level packages(SIP) for applications in defence, aerospace, space, communications, radar and other leading-edge industries. These materials are produced using our proprietary rapid solidification technology, which has been used for the manufacture of many advanced materials,so as to reduce the material weight,enhance the performance,maximize your profit and saving and keep environmental safety.


Advantages of controlled expansion Al-50%Si controlled expansion alloy amplier housings:

● Higher thermal conductivity;

● 1/3 the weight;

● Substituting the Kovar microwave module;

● Fewer manufacturing steps;
