Stay-Silv® 2HP Phos-Copper Brazing Alloy

Stay Silv® 2HP features a higher phosphorus content which provides a narrower melting range and quicker flow. This alloy is designed for use on applications where close, uniform clearance can be maintained. Complies with the EU Reach & RoHS directive.

Traits

• Cost saving, high phosphorus alloy
• Its tighter melting range makes it more fluid
• Medium-range alloy for brazing copper and copper-to-brass
• Brazing range of 1300◦F - 1455◦F (704◦C - 788◦C)
• Fluidity rating 5
• Recommended joint clearance of 0.002 in. - 0.005 in. (0.51 mm - 0.13 mm)
• Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys, including Stay-Silv® 2HP, should not be used if the braze is exposed to sulfur or sulfur compounds in service
• Flux not required for copper brazing as it is self-fluxing. For brazing brass or copper-to-brass Stay-Silv® white flux is suitable for most applications. Harris Eco Smart® boric acid free flux, powder or paste, is an excellent choice to promote sound brazed assemblies
• Complies with the EU Reach & RoHS directive
