The fluxes used for brazing copper joints are different in composition from ... Brazing has been a field of industrial significance specially for heat exchanger and structural joint fabrication (Ref 1,2,3).Though copper and its various alloys are widely used braze materials for joining steels, there are questions on the reliability of the joint in practical applications due to their occasional failure. 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. Use a neutral flame for most brazing jobs that require oxyacetylene gases. It is important to avoid an oxidizing flame, as excess acetylene removes surface oxides from the copper. When this happens, the copper appears bright rather than having a dull or blackened surface.

The "working" elements of active brazing alloys are titanium and zirconium. Because Ti and Zr are very strong acceptors of oxygen (and there is obviously a lot of oxygen present in oxide-form within the sintered matrix of oxide-base ceramic materials), the joining process will depend very much on the ability of titanium/zirconium to react (at brazing … BPS 107-1 has a minimum overlap of the greater of 1/4 inch or 3 times the thickness of the thinner member. Since 0.080 X 3 = 0.240, the tube must be inserted into the socket at least 1/4 inch. 0.25 in).
