OVERVIEW

High-Flow Phos-Copper Alloy for Precision Brazing

Master your copper joints with Harris 0, the go-to phos-copper brazing rod for welders and HVAC professionals who demand fluidity and speed. This BCuP-2 alloy is engineered to flow quickly at brazing temperatures, making it perfect for joints with tight clearances. The 3/32" diameter offers excellent control for medium-sized tubing and fittings, while the 20-inch length ensures you can complete long runs of brazing without constant interruption.

One of the standout features of Harris 0 is its self-fluxing capability on copper base metals. The phosphorus content in the rod reacts with the copper oxides to clean the surface as you braze, creating a clean, strong bond without the mess of external flux. This makes it a favorite for refrigeration lines, air conditioning installs, and general copper plumbing where speed and cleanliness are paramount. The resulting joint is strong, ductile, and corrosion-resistant.

This 25 lb package (SKU 050R) ensures you have a stocked inventory for big jobs. With a solidus of 1310°F and a liquidus of 1475°F, the alloy transitions quickly from solid to liquid, requiring a skilled hand to manage the flow but rewarding the operator with smooth, professional fillets. Whether you are pre-fabbing assemblies in the shop or working in the field, Harris 0 delivers consistent performance that professionals trust.

FAQ

No, Harris 0 is self-fluxing on copper-to-copper joints due to its phosphorus content.

No, phosphorus-bearing alloys like Harris 0 should not be used on ferrous metals as they form brittle phosphides that weaken the joint.

This rod meets the AWS A5.8 classification for BCuP-2.

Harris 0 has a solidus of 1310°F (710°C) and a liquidus of 1475°F (802°C).

Yes, Harris 0 can be used to braze brass, but you must apply a brazing flux (like Stay-Silv white flux) because the self-fluxing action only works on copper.

This specific SKU (050R) is a 25 lb bulk package.

These rods are 3/32 inches in diameter and 20 inches long.

No, Harris 0 is a phos-copper alloy containing approximately 7.1% phosphorus and the balance copper; it contains 0% silver.
