LucasMilhaupt® AL 822 Handy One Brazing Rods Aluminum to Aluminum/Copper .090" x 20" (4 pk)

APPLICATIONS

AL 822 is a low temperature alloy ideal for brazing or soldering aluminum to aluminum or aluminum to copper. Noncorrosive flux does not require removal after brazing. It is ideal for open air heating methods and very easy to use for aluminum brazing in HVAC/R applications.

FEATURES

• The properties of a brazed joint are dependent upon numerous factors including base metal properties, joint design, metallurgical interaction between the base metal and the filler metal. Joint clearances of 0.003 - 0.005 in. (.076-.127 mm) per side are optimum for achieving highest joint strength. Joints with increased clearances can still produce adequate joint strengths depending on final operating conditions. Zinc based alloys offer the highest strength in comparison to other commercially available low temperature brazing alloys often surpassing shear strengths of 18,000 PSI as long as proper joint design techniques are implemented.
