PHOS-COPPER BRAZING ALLOYS
Phos/copper and silver/phos/copper alloys are used to braze copper to copper and
copper to brass. The phosphorus content in these alloys makes them self-fluxing on
copper. When brazing brass or copper to brass, us e Stay-Silv white brazing flux. These
alloys are not recommended for brazing steel or other ferrous metals.
The amount of phosphorus in the phosphorus/copper filler metals (AWS BCuP series) is
the critical factor that determines the melting range of the alloys and thus, how they per-
form. The Harris Products Group is the brazing industries forerunner in developing the
technology to control phosphorus content. This controls alloy melting temperatures so ex-
actly, that brazing operators no longer need to make temperature adjustments from one
batch of filler metals to the next. Operators know that with Harris alloys, the result will be
the same with every batch, every time.
Its technology is so exacting The Harris Products Group guarantees users a Liquidus
temperature variation of no more then plus or minus 6˚F, a much tighter standard than
industry requires. Every package of Harris brazing alloy is clearly marked with the alloy’s
liquidus temperature, and all Harris brazing rods are marked with alloy identification.
Over the decades many things have changed in our industry. But our dedication to making
the world’s purest and most consistent brazing alloys has not changed; we are commit-
ted to giving you the best tool to do your job.
Harris 0
®
Low-cost alloy for many copper-to-copper applications where good fit-up
can be maintained and brazing temperature is not critical.
Stay-Silv
®
5 and Stay-Silv
®
6 Medium-range alloys; Stay-Silv 5 is useful
primarily where fit-up cannot be tightly controlled. Stay-Silv 6 is slightly more fluid and can
be used where closer tolerances are available. Both alloys are somewhat more ductile
than Harris 0.
Dynaflow
®
Premium, medium-range silver alloy, formulated to even tighter
specifications than the Stay-Silv alloys to mirror the performance characteristics of the
15% silver brazing filler metals. Excellent for brazing both tight and poorly-fitted con-
nections, Dynaflow’s proven reliability and acceptance by field service engineers has
made it the leading choice of brazing operators.
