AL 716 is a general purpose brazing filler metal used to join aluminum and aluminum
alloys. When joining dissimilar metals thought should be given to the galvanic potential
between the metals to avoid galvanic corrosion problems.
AL 716 corrosion resistance is satisfactory but somewhat lower than that of AL 718. To
maintain joint integrity on heat treatable Al alloys, the solution temperature must be below
the solidus of the filler metal. To prevent liquidation, it is recommended that the parts be
heated rapidly through the solidus-liquidus temperature range.
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-.127mm) per side are optimum for
achieving highest joint strength. Joints with increased clearances can still produce
adequate joint strengths depending on final operating conditions.
