Flux plays a vital role in virtually all air brazing
processes. Use of the wrong flux or a poor application technique
can have a dramatic effect on joint quality.
Fluxes are classified as corrosive, intermediate
or non-corrosive. The choice depends on the metals being
joined, the melting range of the solder and whether the
residues are to be removed after soldering.
There are also special fluxes for brazing tungsten carbide,
stainless steel brazing, induction brazing, brazing aluminum
bronze, manufacturing flux coated rods, reducing red staining
on brass and brazing refractory metals.

Brazing / Soldering Flux
purpose, low temperature, organic fluoride type
flux for use in silver brazing most ferrous and
non-ferrous metals, stainless tools and carbides.
Molten at 1000 °F and active to a maximum of
1800 °F. It exhibits a long active lift at brazing
temperatures combined with excellent fluidity, and
promotes outstanding adherence. Applications include
automotive, jewelry, musical intstruments, aerospace,
carbide tools, electronics and plumbing. Not recommended
for use on aluminum, magnesium and titanium.
version of the SilverFlux White. Intended for use
where refractory oxides are formed on metals being
heavy-duty, liquid soft soldering flux that is active
between 200 ºF and 600 ºF. It promotes excellent
solderability on both copper based and ferrous alloys,
including tin/antimony, tin/silver solders and stainless
steel. This flux is non-fuming and the residues are
water soluble. Should not be used for electrical or
electronic applications, and is not recommended for
aluminum, magnesium or titanium,
active soldering flux formulated for use with tin/antimony
and tin/silver solders. This paste soldering flux
is a superior flux for most metals including copper,
brass, bronze, steel, stainless steel, galvanized
and Monel alloys. SolderFlux should not be used for
electrical or electronic applications, and is not
recommended for aluminum, magnesium or titanium.
liquid flux for soldering with all soft solders. use
Aufhauser 505 (neutral) flux with any commercial lead-tin,
tin-silver, tin-antimony soft solders. It is a general
purpose, neutral, "noncorrosive" soldering
flux for use on electrical devices, electronic parts,
concealed joints, and for items where corrosion cannot
be tolerated. It is active between 300 ºF and
powder flux recommended for Aluminum 4047 (formerly
718) brazing alloy and other aluminum brazing alloys.
It has a brazing temperature range of 1030 ºF through
1400 ºF. The flux promotes strong braze joints
in aluminum alloys, without melting the parent metals.
It wets the joining surfaces thoroughly and prevents
trapping of aluminum oxide inclusions in the joints.
Applications include HVAC, industrial equipment and
brazing brass, bronze, copper, steel, nickel silver,
and malleable iron. BronzeFlux causes the bronze
to penetrate deeper into the joint, making a stronger
union than is possible with other fluxes. It is
the most efficient brazing flux on the market and
also the most economical.
powder flux for brazing and welding aluminum. A premium
formula flux. Active in a range between 1080 ºF
and 1140 ºF. The powder turns to a clear liquid
when the proper brazing temperature has been attained.
Can also be used as a paste.
powder flux for brazing cast or malleable iron with
bronze rod. Flux11 is active between 1500 ºF
and 2000 ºF. Joints are bright, clean, strong
and free from porosity, owing to the scavenging action
of the flux. Applications include industrial equipment,
marine engines, and maintenance.
high temperature flux, works very well with ferrous
metals, stainless steels, carbides and specialty alloys
containing refractory oxides. Applications include
carbide tools, industrial equipment, mining tools,
fire extinguishers, jobs involving large parts and
long heating cycles.
white granular powder flux. Works well on ferrous,
non-ferrous alloys and stainless steels and is most
suitable for use with low fuming bronze (C681) filler
metal. Entirely free of fluorides, with a high boric
acid content which permits the flux to stick to hot
filler metal rods.
Production Brazing Flux
infused, high speed automation liquid flux for braze-welding
steel and other metals with bronze rods, nickel-silver
rods and silver solders. Flux is dispersed through
the flame. Applications include all-surface brazing
applications, building up shafts and spindles, automotive,
sculpture, jewelry, HVAC and general maintenance.

petroleum gas systems such as MAPP and others.
