TTU969 - Nexalloy ER5356 Aluminum MIG Welding Wire 0.035" - 5lb Spool

Reliable Aluminum Welding for Tough Projects

If you are welding aluminum and need a wire that feeds smoothly and holds up to stress, the Nexalloy ER5356 .035" MIG wire is your go-to solution. Unlike the softer 4043 wires that can buckle and bird-nest in your liner, 5356 is naturally stiffer. This extra rigidity helps the wire push through your torch liner or spool gun with fewer interruptions, keeping your arc stable and your frustration levels low. This 5lb spool is the perfect size for portable jobs or shop use where you need enough material to get the job done without lugging around a massive drum.

This wire is formulated with 5% magnesium, which gives your welds significantly higher strength than standard silicon-based wires. It is the top choice for welding on boat hulls, pontoons, truck beds, and trailers because it stands up incredibly well to saltwater corrosion. If you are building something that needs to look good, 5356 is also the winner; if you plan to anodize your part after welding, this wire will match the color of your base metal much better than other options, which often turn black during the process.

Whether you are repairing a diamond plate toolbox or fabricating a structural frame, this wire delivers consistent penetration and a clean bead profile. Remember to use a clean stainless steel brush on your base material before welding and ensure you are running 100% Argon gas for the best results. With Nexalloy's quality manufacturing, you get a consistent diameter and clean surface finish on the wire, ensuring your contact tips last longer and your welds stay defect-free.
