4043 is an aluminum/silicon filler metal designed for welding heat treatable base metals and is a common choice for welding 6061. 4043 offers good fluidity and less crack sensitivity. It is often used to for repair welding aluminum/silicon cast alloys such as grades 353/A356. 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.Specification Compliance: ANSI/AWS A5.10 Class R/ER 4043, ASME SFA 5.10, QQ-R-566B, AMS 4190 (Chemistry Only)
