BRAZING AND SOLDERING
ALUMINUM
Aluminum can be soldered or brazed if the correct procedure is
followed. Pre cleaning is essential to break up the tough aluminum
oxide film. Thorough brushing with a stainless steel wire brush is
recommended. Most common aluminum alloys such as 1100 and
3003 can be readily soldered or brazed. It should be noted that
some alloys are difficult to join. Dissimilar metal connections may be
subject to galvanic corrosion in certain service conditions.
ALCOR
®
Aluminum alloy with non-corrosive flux inside the wire, thus no
external flux required. Very good fluidity with good capillary attraction.
Post-braze cleaning unnecessary. Its low operating temperature often
makes it a better choice than aluminum silicon alloys for aluminum
coil repair.
AL-SOLDER
®
Forms excellent corrosion-resistant joints on the tough-to-solder
aluminum alloys. Joints all solderable aluminum alloys to each other
and to dissimilar metals, both ferrous and non-ferrous. Also beneficial
as a high-temperature solder on most other metals.
AL-BRAZE
®
Superior brazing alloy for the joining of aluminum-to-aluminum.
Not recommended for brazing aluminum directly to non-aluminum
alloys, as the joint may become brittle. Al-Braze
®
is free flowing with
unequaled capillary attraction, ductility and penetration. Excellent
corrosion resistance.
