Harris Products Group, 0404327, Aluminum MIG Welding Wire, 3/64 in (1.19 mm), Gray (post anodized), 16 lb, ER4043

4043 aluminum GMAW (MIG) welding alloy 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. It is qualified to AWS A5.10 ER4043, ABS, ISO Designation AlSi5. It is commonly used for welding automotive parts, truck trailers and repairing bicycles.

Features

• Lower melting point and more fluidity than the 5XXX series filler alloys
• Designed for welding heat treatable base alloys, specifically 6XXX series alloys
• Embossed on each end for easy identification after use
• Gray (post anodized) color
• Often used to for repair welding aluminum/silicon cast alloys such as grades 353/A356
• Suitable for sustained elevated temperature service, i.e. above 150°F (65°C)
• All position, except vertical down welding
• Common choice for welding 6061
• Low sensitivity to weld cracking with the 6XXX series base alloys

Applications

• Repair welding of aluminum/cast alloys such as grades 353/A356
• bicycle frames
• Automotive components such as frames, drive shafts, parts, truck trailers
• Welding 6XXX series alloys
