Product Description
Premium ERCu De-Oxidized Copper TIG Welding Filler Wire – 2.4mm Diameter
Achieve strong, clean, and porosity-free welds on copper and copper alloy materials with our high-quality ERCu De-Oxidized Copper TIG Filler Wire (2.4mm). Engineered to AWS A5.7 / ASME SFA-5.7 classification standards, this filler wire is the ideal choice for professional welders, fabricators, and industrial workshops working with pure copper base metals.
Manufactured from high-purity copper and alloyed with controlled additions of manganese, silicon, and tin as deoxidizing agents, this ERCu wire minimizes oxygen content in the weld pool — preventing porosity, cracking, and brittleness that commonly occur when welding copper. The result is smooth, consistent bead formation with excellent fusion, high electrical conductivity, and superior mechanical strength.
Key Features
- Grade: ERCu (De-Oxidized Copper) — AWS A5.7 Class ERCu
- Diameter: 2.4mm (0.093 inch) — ideal for medium-to-thick section welding
- Process Compatibility: GTAW / TIG welding (also suitable for OFW/gas welding)
- Deoxidizers: Manganese, Silicon, Titanium/Tin (deoxidizing elements minimize porosity)
- High Purity Copper Base: Ensures excellent electrical and thermal conductivity in the finished weld
- Smooth Surface Finish: Consistent wire diameter for stable arc and uniform feeding
- Low Spatter, Low Porosity: Clean welds with minimal post-weld cleanup
- Straight Length Cut Rods: Precision-cut for TIG welding applications (typically 1000mm length)
Applications
This ERCu 2.4mm TIG filler wire is widely used across industries requiring copper-to-copper joining, including:
- Copper busbars and electrical conductors
- Copper pipes, tanks, and vessels
- Heat exchangers and condensers
- Electrical and power generation equipment
- Copper sheet metal fabrication
- Ship building and marine copper components
- HVAC and refrigeration copper assemblies
- General copper alloy repair and maintenance welding
