Advanced Al-Si Alloy For Telecom System
Nov 13, 2017

Aluminum is the most common versatile material extremely for aerospace applications,such as sensor mounts, or small-ordinance initiators and high-power T/R modulus.Current housings for RF modules are generally made from either Kovar or 6061 Al.Because type 6061-T6 has the excellent properties of economics, rigidity, and ease of machining.Thus,Al 6061 is employed as packaging material due to these intricate features.The controlled expansion spray deposited Si-Al housing materials combine a low CTE approaching that of Kovar, with a thermal conductivity approaching that of 6061 Al, and a density that is less than that of both materials.Keep in mind that if you choose to work with inventory materials, we can build your sealing, parts or components in 2-3 days. Except this aspect, we can always order other Grades if your design requires a different type.
