SILVALOY 2 is extremely fluid at brazing temperatures and will penetrate joint with very little clearance. Best results are obtained with clearances of .001-.003". Melting of SILVALOY 2 is virtually complete at 1350°F (732°C). Best results are obtained when brazing slightly above this temperature. The phosphorous content of SILVALOY 2 acts as a fluxing agent and no flux is necessary when brazing copper to copper joints. However, when used with one of the other brazeable metals, a brazing flux must be used to promote wetting, bonding, and flow throughout the joint.

Applications
SILVALOY 2 is used for the brazing of copper and copper alloys, brass and bronze. It is primarily used for the joining of copper-to-copper on vibration free joints. It is very effective for joining tight fitting copper pipe and tubing. SILVALOY 2 should not be used on ferrous metals or alloys containing more than 10% nickel due to the formation of brittle intermetallic phosphide compounds.
