Cobalt alloy bars are metallic bars composed primarily of cobalt with various other alloying elements such as chromium, nickel, tungsten and molybdenum for additional reinforcement. Cobalt alloy bars are known for their exceptional mechanical properties as well as resistance against high temperature resistance and corrosion - qualities which make them invaluable materials in various industrial settings.
Cobalt alloy bars stand out as being highly resilient due to their extraordinary strength and hardness at elevated temperatures, making them suitable for applications requiring durability in harsh conditions and reliable performance. Furthermore, cobalt alloys exhibit exceptional wear resistance making them suitable for components in environments subjected to high levels of mechanical stress or exposure to aggressive environments.
Cobalt alloy bars possess exceptional corrosion resistance in harsh chemical environments. As such, their use is increasingly sought-after within industries like petrochemistry, chemical processing and marine engineering where exposure to corrosion-causing agents may occur frequently.
Cobalt alloy bars stand out as being exceptionally thermal stable, maintaining their mechanical properties at higher temperatures, which make them suitable for use in environments like gas turbines, aerospace components and high temperature furnaces.
Cobalt alloy bars versatility lies in their outstanding machinability and weldability, which enables easy fabrication and customization to meet specific application needs. This characteristic increases their use across manufacturing processes such as machining, forging and welding.
Cobalt alloy bars find wide use across numerous industries. Their applications in aerospace and gas turbine engines include making components like turbine blades, combustion chambers and exhaust systems due to their superior temperature resistance and mechanical strength; in medical use cobalt alloys find application in orthopedic implants, dental prosthetics and surgical instruments due to biocompatibility and corrosion resistance properties.
Cobalt alloy bars have long been recognized in the oil and gas industry for use in equipment exposed to harsh drilling environments, including valves, pumps and drilling tools used in drilling operations. Cobalt bars ensure reliable performance as well as extended service lives by resisting corrosion-producing fluids or conditions while resisting wear-and-tear wear from fluid-borne particles in such equipment.

Melting and Casting
Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.
Forming
Most cast steel is formed by hot rolling—the slab, bloom, or billet is heated and passed through large rollers, stretching out the steel into a longer, thinner form.
Heat treatment
Heat treatment strengthens rolled Cobalt Alloy by recrystallizing the deformed microstructure. Most Cobalt Alloy is heat treated by annealing.
Descaling
A rolled piece of Cobalt Alloy acquires a layer of oxidized “mill scale,” which needs to be washed away to restore a shiny surface finish.
Cutting or Machining
Cobalt Alloy is cut to a specified shape and size. The Cobalt Alloy can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
