EXCUSIA00000350M00 - Exocor ERCuSi-A Silicon Bronze MIG Wire .035 30lb

Master Dissimilar Metals with Exocor Silicon Bronze

For welders tackling complex projects that involve joining copper to steel or repairing galvanized sheet metal, the Exocor Silicon Bronze .035" MIG Wire is a game-changer. This "Si-Bronze" wire is the secret weapon in many automotive body shops and custom fabrication garages. Unlike standard steel wire, Silicon Bronze melts at a lower temperature, allowing for MIG brazing rather than fusion welding. This is incredibly beneficial when working on car bodies because it doesn't burn away the zinc coating on galvanized steel as aggressively as mild steel wire does, preserving the corrosion resistance of the base metal and reducing warping on thin panels.

The 0.035-inch diameter is the perfect middle ground, offering enough deposition for structural surfacing while remaining controllable for thinner gauge work. When you run this wire with 100% Argon, you'll notice a distinctively smooth, soft arc that wets out beautifully. The puddle is fluid but manageable, creating a classic gold-colored bead that looks fantastic and requires minimal post-weld grinding. It is also an excellent choice for artistic welding and sculpture work where color matching to copper or bronze components is desired.

Exocor has packaged this wire in a substantial 30lb spool, meaning you can keep welding longer without interruption. Whether you are building custom furniture, repairing cast iron components (where it can be used as an alternative to nickel in non-critical stress areas), or overlaying a bearing surface, this wire feeds reliably. The precision winding prevents the dreaded "bird's nest" at the drive rolls, letting you focus on your travel speed and torch angle. If your shop handles diverse materials, keeping a spool of Exocor ERCuSi-A on hand ensures you are ready for everything from cast copper repairs to joining steel brackets to copper pipes.
