Stay-Silv® 2LP Phos-Copper Brazing Alloy

Stay-Silv® 2LP is an economical, phos-copper brazing filler metal alloy. It features a lower phosphorus content than Stay-Silv® 2 yielding a wider melting range. This improves the alloy's ability to fill non-uniform clearances. Complies with the EU Reach & RoHS directive. Complies with ISO 17672 CuP 279 and EN 1044 CP 105

Traits

• Cost saving, low phosphorus alloy
• Wider melting range than Stay-Silv® 2
• Can fill non-uniform clearances
• Brazing range of 1350◦F - 1550◦F (732◦C - 843◦C)
• Fluidity rating 3
• Recommended joint clearance of 0.003 in. - 0.006 in. (0.08 mm - 0.15 mm)
• Corrosion resistance is generally similar to the copper base metal, but phosphorus containing alloys, including Stay-Silv® 2LP, 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
