Baienwei is a professional manufacturer producing Al-Si alloys(also called CE alloys overseas).
Other parts where needs low CTE and high stiffness
Advantage of AlSi alloys:
Low CTE, tailored from 7-20ppm/℃, compatible with GaAs, alumina and GaN etc;
Low density, lightest thermal managment and packaging alloy;
High thermal conductivity;
Easy to be machined, plated and welded.
Directly replace Kovar, AlSiC, Cu-W, Cu-Mo in many application.
