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 connections. Dynaflow’s
®
proven reliability and acceptance by field
service engineers has made it the leading choice of brazing operators.
STAY-SILV
®
15
The industry standard for air conditioning and refrigeration applications.
Still widely used, but now often replaced by Dynaflow
®
in many HVAC/R
applications.
BLOCKADE
®
Blockade’s
®
unique silicon addition offers significant advantages over
phos/copper and silver/phos/copper, (BCuP), brazing alloys. Among the
benefits are: bright alloy color during cooling that allows visual verification
of a good braze joint, improved ductility over BCuP-2 alloy, reduced brazing
temperature, and reduced material costs. It is often used with Stay-Silv
®
white brazing flux as a replacement for high silver alloys when brazing brass.

PHOS-COPPER BRAZING ALLOYS

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 perform. The Harris Products Group is the
brazing industry’s forerunner in developing the technology to control
phosphorus content. This controls alloy melting temperatures so precisely
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.
Over the decades many things have changed in the industry. However,
Harris’ dedication to manufacturing the world’s purest and most
consistent brazing alloys has not changed. Harris is committed to
providing the best products every time, all the time, so all jobs are
completed successfully.
THE HARRIS
PRODUCTS GROUP
guarantees users a liquidus
temperature variation
of no more than plus or
minus 6˚F, a much
tighter standard than the
industry requires.
