AL 716
AWS: BAlSi-3
AL 716 is a general purpose filler metal for joining aluminum and aluminum alloys. Corrosion resistance of AL 716 is less than that of AL 718. Solution temperature during heat treating must be below the solidus of the braze alloy in order to ensure integrity of the joint is maintained.
Available Forms
Wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste.
Characteristics
AL 716 has a wider melt range than that of 718, therefore assemblies should be heated quickly through the melt range in order to prevent liquation. The increased silicon content compared to other aluminum filler metals provides increased fluidity as well as reduced shrinkage.
Properties
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” (0.076-0.127 mm) per side ideal for achieving the highest joint strength in aluminum brazed assemblies.
