Aluminum TIG welding alloy
Qualified to AWS A5.10 R4043, ABS, ISO Designation AlSi5, Alloy 4043 is a 5% silicon alloy used to weld heat-treatable base alloys. It is most often used to weld the 6XXX series of alloys. The silicon addition improves puddle fluidity, producing an appealing bead profile. It is less crack-sensitive on the 6XXX series than other welding alloys.
Typical Application: Common applications are automotive parts, truck trailers and bicycles. It is also ideally suited for brazing thin aluminum sheet and tubing.
