Bossweld Silicon bronze copper alloy MIG Wire, engineered for inert gas arc welding of copper, copper‑silicon and copper‑zinc base metals to themselves or to steel, with excellent ductility and smooth arc behaviour.

Key Features:

• Classification AWS A5.7 ERCuSi-A
• Copper silicon alloy filler wire providing excellent weldability on copper-based materials
• Precision layer-wound wire for smooth feeding and stable arc performance
• High ductility and lower strength enabling smooth fusion on thin and delicate materials
• All-position welding capability for flexibility across joint configurations
• Ideal for automotive panel repair, fencing, hot water systems and marine fabrication
• Compatible with inert shielding gases for clean, stable welds with minimal contamination
