4043 Aluminum MIG Welding Wire, 0.035" Size, 1 lb. Spool, 1065 F Solidus, 1170 F Liquidus, 350-475 ipm Wire Feed Speed, 100% Argon Shielding Gas
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, ABS / CWB / Designation AlSi5, Alloy 4043 is an all-position 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.Specification Compliance: ANSI/AWS A5.10 Class R/ER 4043, ASME SFA 5.10, QQ-R-566B, AMS 4190 (Chemistry Only)
