ESTIMATING AMOUNTS OF
BRAZING ALLOYS REQUIRED
Locate the tube diameter to be joined and the wire size to be used.
Where the row and the column intersect is the approximate length in
inches of alloy required per joint.
Multiply the length of the alloy needed per joint by the total number of
joints.
To convert the total length to pounds or troy ounces, divide by the inches
of alloy/lb. in row A or the inches of alloy/troy oz. in row B.

The Harris Products Group
manufactures its complete line
of cadmium-free, high silver
brazing alloys with the same
attention to quality found in their
phosphorus / copper products.
Only the purest metals are used.
Precision production procedures
ensure consistency in product
quality and performance.
Safety-Silv
®
alloys are strongly
recommended as replacements
for all cadmium-bearing brazing
filler metals.
SAFETY-SILV
®
56
This high silver (56%)
content alloy makes first-
quality brazes. It is free-
flowing with unequaled
capillary attraction and
deep penetration. Ductility
is high and corrosion
resistance is suitable for
all but strong chemical
applications. NSF 51
listed for use with food
equipment materials. The
silver color is an excellent
match to stainless
steel and silverware
applications.
SAFETY-SILV
®
45T
Performs like a 45%
silver, cadmium-bearing
alloy. Lower melting
temperature than Safety-
Silv
®
45. Excellent
fillet forming qualities.
Produces high-strength,
ductile joints. Listed with
NSF 51 listed for use with
food equipment materials.
SAFETY-SILV
®
45
Excellent general purpose
nontoxic brazing alloy.
Good ductility and capillary
flow. Color is silver to light
