Harris Dynaflow Brazing Rod 1/8 in 6% Silver

This Harris Dynaflow brazing rod measures 20 in long with an overall diameter of .05 in x 1/8 in. It contains 6 percent silver in a phos-copper alloy suited for brass-to-brass, brass-to-copper, and copper-to-copper joining. The solidus temperature is 1190 Degrees F and the liquidus is 1465 Degrees F. It is sold new in a pack of seven rods.

Who this suits and who should look elsewhere

HVAC technicians and plumbers needing a 6 percent silver phos-copper rod for copper and brass fittings will find this alloy matches the 1190 to 1465 Degrees F melting range. Buyers who require an AWS-classified filler metal or a different silver percentage for specific code work should look elsewhere.

Deciding specification — 6 percent silver content

The 6 percent silver content defines the fluidity rating of 3 and the melting range between 1190 and 1465 Degrees F. This composition determines whether the rod meets the joint strength and flow requirements for your brazing application.

Questions about this item

How can I confirm the rod is flowing correctly at the 1190 °F solidus temperature?

The alloy becomes fully liquid at 1465 °F; a smooth, shiny fillet at the joint indicates proper flow.

What comes in the PK7 pack and do I need separate flux?

The pack contains seven bare 1/8 in × 20 in rods; no flux is included, so purchase a compatible phosphorus-copper flux separately.

Should I choose the 6 % silver Dynaflow or a different alloy for copper-to-copper work?

The 6 % silver Phos-Copper Dynaflow is rated for copper-to-copper, brass-to-copper and brass-to-brass joints.
