TTV020 - Nexalloy 5356 Aluminum MIG Wire 0.045" - 5lb Spool

Reliable Aluminum Welding for Tough Environments

When your project demands strength and durability in harsh conditions, Nexalloy 5356 Aluminum MIG Wire is the filler metal you can trust. This 5lb spool of 0.045" wire is engineered for welders who need consistent feedability and professional results. Whether you are fabricating a new aluminum boat hull, repairing a trailer, or building a custom automotive frame, this wire delivers the performance you need to get the job done right.

Built for the Marine World

Saltwater is the enemy of metal, but Nexalloy 5356 fights back. Thanks to its unique 5% magnesium formula enriched with titanium and chrome, this wire offers superior corrosion resistance. It is widely considered the best choice for any welding application that will be exposed to sea air or saltwater. If you are working on docks, pontoons, or marine hardware, this is the wire that ensures your welds last as long as the base metal.

Strength and Aesthetics

Beyond its toughness, Nexalloy 5356 is known for its excellent feedability through standard MIG guns, reducing bird-nesting and downtime. It produces a clean, bright weld bead that matches the color of the base metal exceptionally well after anodizing—unlike 4043 wire, which can turn dark gray. With high shear strength and great crack resistance, it is the go-to solution for welding 5000 and 6000 series aluminum alloys. Load up your spool gun or push-pull system with Nexalloy 5356 and experience the difference in arc stability and weld quality.
