4043 aluminum 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
- Aluminum filler materials are silicon-aluminum types for welding of 6052 and 6063 types; in some cases, other aluminums are also welded with this type.
- Shaved for ultimate cleanliness.
- Optimized to reduce smoke & fumes.
- 4043 aluminum/silicon GMAW (MIG) welding alloy
- Designed for welding heat treatable base alloys, specifically 6XXX series alloys
- Lower melting point and more fluidity than 5XXX series filler alloys
- Low sensitivity to weld cracking with 6XXX series base alloys
- Suitable for sustained elevated temperature service, i.e. above 150°F (65°C)
- All position, except vertical down welding
- Gray (post anodized) color
