OK Tigrod 12.64

A copper coated, G4Si1/ER70S-6 rod designed for GTAW of general structural and engineering unalloyed and low-alloyed carbon-manganese steels. It features slightly higher silicon and manganese content to increase weld metal strength and promote smooth, sound welds with low sensitivity to surface impurities.

Key Features

• Copper-coated TIG rod for improved arc stability
• G4Si1/ER70S-6 classification with enhanced Si and Mn levels
• Low sensitivity to rust, oil, and mill scale
• Delivers smooth, consistent weld beads
• Available in standard 1000mm lengths and 5kg packs

Specifications

• Classifications: EN ISO 636-A W 46 5 4Si1, AWS A5.18 ER70S-6
• Alloy Type: Carbon-manganese steel
• Shielding Gas: Argon (I1 per EN ISO 14175)
• Typical Composition: 0.074% C, 1.68% Mn, 0.95% Si
