Harris Products Group, 2H520R, Phos-Copper Brazing Alloy, 1300-1455 F, Self-Fluxing, Medium-Range

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.

Features

• Its tighter melting range makes it more fluid
• Complies with the EU Reach & RoHS directive
• Medium-range alloy for brazing copper and copper-to-brass
• Brazing range of 1300◦F - 1455◦F (704◦C - 788◦C)
• 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
• 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
• Recommended joint clearance of 0.002 in. - 0.005 in. (0.51 mm - 0.13 mm)
• Cost saving, high phosphorus alloy
• Fluidity rating 5

• Weight: 1.03 lbs
• Melting Range: 1300 F - 1455 F (704 C - 788 C)
• Phosphorus Content: 7.3% - 7.4%
• Silver Content: 1.8% - 2.2%
• Copper Content: Remainder
• Other Elements: 0.15%
• Corrosion Resistance: Similar to copper; avoid sulfur exposure
• Recommended Joint Clearance: 0.002 in - 0.005 in (0.51 mm - 0.13 mm)
• Fluidity Rating: 5
• Compliance: EU Reach, RoHS
