AL 716 TECHNICAL DATA
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.
PROPERTIES OF BRAZED JOINTS
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.
