Brazing Aluminum to Copper Brazing aluminum to copper has wide use in the refrigeration industry where copper pipes are brazed to aluminum roll-bond pipes or panels. To bond aluminum and copper, a flame brazing would be applicable or applying a low-melting flux with a low-melting filler metal.
Nov 22, 2021 Brazing is used widely for the joining of copper and copper alloys, with the exception of aluminum bronzes containing greater than 10% aluminum and alloys containing greater than 3% lead. Brazing of copper is used extensively in the electrical manufacturing industry, and in the building mechanical services and HVAC fields.
Brazing is a joining process wherein metals are bonded together using a filler metal with a melting (liquidus) tempera-ture greater than 450 °C (840 °F), but lower than the melting temperature of the base metal. Filler metals are generally alloys of silver (Ag), aluminum (Al), gold (Au), copper (Cu), cobalt (Co) or
May 05, 2008 working on an old GE RTU that I did a compressor replacement on and the line going from the roto lock fitting into the evaporator coil broke loose. Was wondering if any one had any insite on repairing the copper line going to the aluminum coil. If it was just copper I could braze it but being copper to aluminum poses a tricky situation. Any help would be greatly appreciated. thanks in
