4043 is a great choice for the welding of heat-treatable base alloys and more specifically the 6XXX series alloys. It has a lower melting point and more fluidity than the 5XXX series filler alloys and is preferred by welders because of its favorable operating characteristics. ER4043 type wires are also less sensitive to weld cracking with the 6XXX series base alloys. RADNOR® 4043 is suitable for sustained elevated temperature service, i.e. above 150° F.
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.
- 4051 contains silicon additives which results in improved fluidity of the weld pool
- 4051 provides a bright weld finish making it the most popular aluminum type
- 120 spools per pallet
- Superior wire surface finish for the best feedability and arc performance
- Optimal manufacturing process to precisely control chemical composition
- State-of-the-art testing equipment to ensure trouble-free performance of the weld wire
- Manufactured under a quality system certified to ISO 9001 requirements
Applications
- For welding 6XXX alloys, and most casting alloys
- Good all purpose filler alloy
- Automotive components such as frame and drive shafts
- Bicycle frames
