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.

The governing rule for alu-minum brazing is that the filler metal must liquidize before the base metal reaches its solidus temperature. This tem-perature difference may be as small as 10°-18°F (5°-10°C).
