Filler metals for Brazing-beryllium are mainly selected from zinc, aluminum and silver alloys. Aluminum or its alloys with 7.5 or 12.5% Silicon are normally used for providing acceptable strength in the joints up to 175 °C (345 °F). However due to poor flow in capillary joints, the filler has to be preplaced.
