Product identity
This Harris Stay-Silv 5 brazing rod is a phos-copper alloy with five percent silver content. It is supplied as bare rods measuring 0.05 inches by 1/8 inch diameter and 20 inches long. The product carries AWS BCuP-3 and ISO 17672 CuP 281 classifications for copper and brass joining.
Compatibility check
Verify that your application requires a filler metal melting between 1,190 and 1,500 degrees Fahrenheit. Confirm the base metals are brass-to-brass, brass-to-copper or copper-to-copper. Ensure your torch setup can reach the 1,190 degree solidus temperature for proper flow.
Suitability
This rod suits technicians joining copper and brass components in HVAC, plumbing or refrigeration work where a 5 percent silver alloy is specified. It is not for buyers who need a higher silver content for wider clearances, nor for those joining ferrous metals such as steel or stainless steel.

Questions about this item
What comes in the PK7 pack and do I need flux?
The pack contains seven bare Stay-Silv 5 rods, 1/8 in diameter and 20 in long; no flux is included so buy a compatible phosphorus-copper flux separately.
Which alloy version suits copper-to-copper joints?
Stay-Silv 5 with 5 % silver (AWS BCuP-3) is made for copper-to-copper, brass-to-copper and brass-to-brass work.
What does the 1190-1500 °F range mean on the job?
The rods melt between 1190 °F solidus and 1500 °F liquidus, giving a working window around 1350 °F for capillary flow in copper joints.
