Description
🔧 Cobalt 12 TIG Wire 6.4mm – 2000mm Rods, 5kg Pack for Extreme Wear Resistance
The Cobalt 12 TIG wire (ERCoCr-B) in 6.4mm x 2000mm rods is designed for TIG welding applications that require excellent wear resistance combined with good impact strength. Packaged in a 5kg bundle, this wire is ideal for restoring or fabricating components exposed to high temperatures and metal-to-metal contact.
Manufactured from a cobalt-chromium-tungsten alloy, this rod offers a hard and corrosion-resistant weld deposit. Compared to other cobalt alloys like Cobalt 6, this version provides increased hardness and improved performance in abrasive environments. It retains its properties at elevated temperatures up to 900°C, making it ideal for high-demand industries.
💪 Ideal Use Cases for Cobalt 12 TIG Wire
Cobalt 12 rods are commonly used for:
-
Hot forming tools, shears, and punches
-
Valve seats and pump shafts
-
High-pressure dies and nozzles
-
Components in turbine and chemical plants
-
Sliding parts exposed to friction and thermal cycling
This alloy’s ability to resist seizing, galling, and oxidation helps extend component life in tough operating conditions. When performance and longevity matter, Cobalt 12 TIG wire is a trusted choice.
⚙️ Welding Best Practices
For optimal results, use Argon shielding gas with a direct current electrode negative (DCEN) setup. Recommended amperage is between 130 and 180 amps, depending on joint type and material thickness.
Welding tips:
-
Thoroughly clean base metals before welding
-
Use controlled heat input to avoid stress cracking
-
Allow slow cooling between passes for best metallurgical results
