Premium Silicon Bronze MIG Wire | 1.0mm Diameter | Braze Welding & Joining

High-performance 1.0mm Silicon Bronze MIG welding wire, engineered for braze welding, joining, and surfacing applications on steel, galvanized steel, and copper alloys. This low-fume, corrosion-resistant filler wire is a top choice for automotive body repair, sheet metal fabrication, HVAC ductwork, and general metal joining where minimal heat distortion and clean welds are essential.

Key Features

  • Diameter: 1.0mm (0.039") — ideal for thin-gauge sheet metal and precision MIG/GMAW work
  • Alloy Composition: Copper-based silicon bronze (typically ERCuSi-A), offering excellent wetting action and flow characteristics
  • Low Spatter, Low Fume: Produces clean, smooth beads with minimal spatter for reduced post-weld cleanup
  • Corrosion Resistant: Superior resistance to atmospheric and saltwater corrosion, making it suitable for marine and outdoor applications
  • Excellent Color Match: Bronze-gold finish blends well on copper, brass, and bronze base metals
  • Reduced Heat Input: Lower melting point than steel wires minimizes warping and burn-through on thin sheet metal

Common Applications

  • Automotive body panel repair and restoration
  • Galvanized and coated steel joining (brazing prevents zinc fume issues)
  • Sheet metal fabrication and HVAC duct work
  • Bicycle frame building
  • Copper, brass, and bronze fabrication
  • Marine hardware and fittings
  • Art metalwork and sculpture fabrication

Why Choose This Silicon Bronze MIG Wire?

Whether you're brazing galvanized steel without burning off the zinc coating, restoring a vintage car body, or fabricating custom metal art, this 1.0mm silicon bronze wire delivers consistent feedability, strong braze joints, and a professional-grade finish. Its fine 1.0mm diameter makes it especially well-suited to thin sheet metal and detailed fabrication work where precision and control matter most.


This product is priced “per KG”. The minimum quantity available to purchase is shown in the "Pack Qty". When welding Silicon bronze wire using a Mig welder - use an Argon + 10-15% Co2 gas mixture
