The comparison between AlSi and AlSiC


  • AlSiC has low density, low CTE, high thermal conductivity, but for the reasons that its too hard to be machined by common tools and the surface is hard to be plated, the applications of it is limited.

  • Baienwei AlSi alloys have the advantages of controlled expansion Low CTE, high thermal conductivity, easy to be machined, plated and welded, can directly replace Kovar, Cu-W, Cu-Mo, Ti in some applications.
