Brazing rod for copper and brass
Harris Stay-Silv 15 brazing rods contain 15 percent silver in a phos-copper alloy classified as AWS BCuP-5. Each rod measures .050 by 1/8 by 20 inches and comes in a seven-piece pack. The rods join copper to copper, brass to copper or brass to brass without separate flux.
Melting range and flow
Solidus is 1190 degrees F and liquidus is 1480 degrees F, giving a fluidity rating of 3 for smooth capillary action. The alloy flows freely at brazing temperature and solidifies cleanly on cooling. No flux is required when joining copper to copper.
When to choose this alloy
The 15 percent silver content suits general-purpose HVAC, refrigeration and plumbing joints where good strength and ductility are needed. It is not intended for ferrous metals, high-vibration structural joints or applications that require a higher silver grade for narrower clearances.

Questions about this item
How do I install the 0.050 x 1/8 inch Stay-Silv 15 rod for copper-to-copper joints, and what step is often missed?
Heat the joint evenly until the base metal reaches 1,190–1,480 °F so the rod flows by capillary action; the step often missed is cleaning oxides off both surfaces before heating.
What maintenance or replacement will the Stay-Silv 15 brazing rod need after repeated use?
The rods are consumable; each 20-inch length is used up during brazing, so you simply replace the pack when the seven rods are gone.
What limit appears first when making many joints in succession with this phos-copper alloy?
The operator’s heat tolerance and the workpiece reaching 1,480 °F liquidus become the practical limits; the alloy itself does not degrade during sustained use.
