Advantages of cobalt alloy welding rods:

• Produced by horizontal continuous casting.
• Excellent surfacing performance.
• It has good high-temperature strength and wear resistance, high-temperature resistance, impact resistance, and specific corrosion resistance.

Applications:

• Argon arc welding, oxyacetylene welding, etc.
• It can be used for surface treatment of parts and components in extrusion dies, turbine blades, exhaust valves of internal combustion engines, oil drilling tools, marine engineering, petroleum industry, coal, oil refining, chemical engineering, boilers and other industries.

SYTOP cobalt-based alloy is a range of cobalt-chromium-tungsten alloys with wear, corrosion and high thermal resistance. It is widely used in oil & gas, machinery, wood cutting, automotive, paper and food processing industry, etc.

Other cobalt alloy products can be customized according to your requirements.
