Frequently Asked Questions

What is HARRIS Phos Copper brazing alloy used for?

HARRIS Phos Copper brazing alloy (BCuP-3, Stay-Silv 5) is used for joining copper-to-copper tubing and fittings in HVAC, refrigeration, and plumbing systems. Its self-fluxing properties on copper eliminate the need for separate flux, making it ideal for high-strength, leak-tight joints in industrial piping.

What are the specifications of HARRIS Stay-Silv 5 brazing rods?

The HARRIS Stay-Silv 5 brazing rods are BCuP-3 composition, bare, measuring 0.05 in x 1/8 in x 20 in. They are packaged as 7 rods per pack (MPN 5620FMPOP). This phos-copper alloy contains 5% silver and is designed for copper-to-copper brazing without flux.

Where to buy HARRIS brazing alloy in worldwide?

How to select the right HARRIS brazing rod for copper joints?

For copper-to-copper joints, HARRIS Stay-Silv 5 (BCuP-3) is a common choice due to its self-fluxing action and good flow. Ensure rod diameter matches joint clearance—0.05 in rods suit tight gaps. Always clean surfaces and heat evenly. For dissimilar metals, consult a brazing guide.
