Plumbing: TechCorner
The melting point of copper (Cu) alloy UNS C12200 is 1,981°F/1082°C. As such, the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature. The basic difference between soldering and brazing is the temperature necessary to melt the filler metal.
