Stellite's™ Cobalt-Based Alloys
Stellite's™ cobalt-based alloys are available in various forms, including rods, electrodes, wire, and powder. These alloys are primarily used for wear-resistant applications and can be applied via any standard fusion welding process or HVOF spraying, making them ideal for hardfacing.
Cobalt alloys are the most widely used wear-resistant hardfacing materials on the market. Their unique combination of wear resistance, strength, and corrosion resistance allows them to perform exceptionally well in harsh environments. They are specifically chosen for their superior resistance to multiple wear types, including:
Adhesive wear
Abrasion
Erosion
Contact fatigue
Thermal shock
Cavitation wear
Corrosion and oxidation
The ability of cobalt alloys to retain these properties under extreme conditions solidifies their unmatched position in wear technology.
