Frequently Asked Questions

What is HARRIS Stay-Silv 15 brazing alloy used for?

HARRIS Stay-Silv 15 (BCuP-5) is a phos-copper brazing alloy with 15% silver, used for joining copper-to-copper and copper-to-brass in HVAC, refrigeration, and plumbing systems. It flows freely without flux on copper joints, making it ideal for tight-fitting assemblies.

What are the specifications of HARRIS 15620S1 brazing rods?

The HARRIS 15620S1 brazing rods are Stay-Silv 15 grade (BCuP-5), supplied as bare rods measuring 1/8 in x 1/8 in x 20 in in an 11-pack. They contain 15% silver. Tensile and yield strengths are not rated by the manufacturer.

Where to buy HARRIS Stay-Silv 15 brazing rods worldwide?

How to select the right phos-copper brazing alloy for copper joints?

For copper-to-copper joints, a phos-copper alloy like HARRIS Stay-Silv 15 (BCuP-5) is self-fluxing and provides strong capillary flow. For copper-to-brass or copper-to-steel, a higher-silver alloy may be needed. Always match the alloy's melting range to your base metals and joint clearance.
