Cobalt (Co)-based alloys are wear resistant, corrosion resistant, and heat resistant (strong even at high temperatures). Cobalt is similar in size, melting point and density to nickel but is less susceptible to hot corrosion. Its useful for low stress, long life at high temperatures up to 1200°F. The softer and tougher compositions are used for high-temperature applications, such as gas-turbine vanes, while the harder grades are used for resistance to wear.
