Premium Silicon Bronze MIG Welding Wire – ER CuSi-A | 0.9mm | 13.6kg Spool
Achieve clean, strong, corrosion-resistant welds with this Silicon Bronze MIG welding wire, classified ER CuSi-A. Engineered for brazing and joining applications across automotive, sheet metal, HVAC, and general fabrication industries, this 0.9mm diameter wire is supplied on a convenient 13.6kg (30lb) spool — ideal for high-volume production runs and professional welding shops looking to minimize downtime from spool changes.
Key Features
- Alloy Type: ER CuSi-A (Silicon Bronze) — a copper-based filler wire containing approximately 3% silicon, offering excellent fluidity and low fuming characteristics
- Wire Diameter: 0.9mm (0.035") — suited for thin-gauge and medium-thickness materials
- Spool Weight: 13.6kg (30lb) — reduces the frequency of spool changeovers on long production runs
- Process Compatibility: MIG (GMAW) and can also be used for TIG (GTAW) brazing applications
- Base Metals: Ideal for joining galvanized steel, coated steel, copper, brass, and bronze — commonly used in braze welding applications where heat control and reduced distortion are critical
Why Choose Silicon Bronze ER CuSi-A Wire?
- Low Fuming, Low Spatter: Produces cleaner welds with minimal cleanup, improving productivity and workplace air quality
- Excellent for Galvanized & Coated Steels: The lower melting point compared to steel filler wires reduces zinc burn-off, preserving the galvanized coating and minimizing distortion on thin sheet metal
- Superior Corrosion Resistance: Silicon bronze deposits resist corrosion in marine, automotive, and outdoor environments
- Smooth Wire Feeding: Consistent diameter tolerance and winding ensure reliable, tangle-free feeding through MIG guns and liners
- Versatile Applications: Widely used in auto body repair, exhaust systems, sheet metal fabrication, bronze/copper joining, and decorative metalwork
Typical Applications
- Automotive body panel repair and restoration
- Galvanized steel fabrication (ductwork, roofing, cabinets)
- Joining dissimilar metals (steel to copper/brass)
- Exhaust and muffler repair
- Marine and outdoor metal fixtures
- Bronze and copper alloy fabrication
