The Application Of AlSi50

AlSi50, also called CE11 in many countries, is the most common used AlSi alloys.


Advantages: 

  • Light weight: only about 1/3 the weight of Kovar;

  • Low CTE: 7-20ppm/℃, compatible with GaAs,Alumina,GaN etc;

  • High thermal conductivity: up to 180W/mK;

  • Easy to be machined: CNC/EDM

  • Easy to be plated: can be plated as common aluminum alloys;

  • Easy to be welded: Baienwei AlSi alloys have high welding finish rate.


Applications:

  • Amplifier housings;

  • Transmitter modules;

  • Receiver modules;

  • Laser combiner;

  • Optical modules;

  • Wafers
