Description

Cigweld Autocraft Deoxidised Copper MIG Wire 13kg

The Cigweld Autocraft Deoxidised Copper MIG Wire 13kg is a versatile 98% pure copper alloy (ERCu classification) designed for Gas Metal Arc Welding (GMAW) of deoxidised copper and electrolytic tough pitch copper components. Engineered for reliable copper-to-copper and dissimilar metal welding, this premium copper MIG wire is ideal for fabrication, repair and overlay applications where conductivity and corrosion resistance are critical.

Classified to:

• AWS/ASME-SFA A5.7: ERCu

Autocraft Deoxidised Copper produces a high purity weld deposit suitable for electrical and industrial applications requiring consistent copper performance.

Designed for Copper & Dissimilar Metal Welding

This wire is recommended for the GMAW welding of:

• Deoxidised copper components
• Electrolytic tough pitch copper
• Copper castings
• Galvanised steels
• Dissimilar mild steel to deoxidised copper joints

It is particularly suited for lower strength welding applications where high structural strength is not required, such as joining copper to galvanised or mild steel components.

Typical applications include:

• Copper transformer connectors
• Copper bus bars
• Billet moulds
• Heater elements
• Corrosion resistant overlay applications

Mechanical & Electrical Properties

Typical all-weld metal properties using welding grade Argon shielding gas include:

• 0.2% Proof Stress: 55 MPa
• Tensile Strength: 200 MPa
• Elongation: 30%
• Electrical Conductivity: 40% IACS
• Hardness: 55 BHN
• Weld Metal Density: 7.47 x 10³ kg/m³

These characteristics make Autocraft Deoxidised Copper ideal for applications requiring good ductility and electrical performance.

Recommended Shielding Gas

For optimal performance:

• Welding grade Argon (SG-A / I1)
• Argon + Helium (25%)
• Helium + Argon (25%)

Operating & Packaging Data
