Product Description

UMCo50 with Excellent Thermal Shock Resistance and Wear Resistance


Main Features
UMCo50 is a heat-resistant cobalt alloy that has excellent thermal shock resistance and wear resistance. It also shows great strength against sulfur-and vanadium-attacks. Another feature is its higher melting point compared to other cobalt base or nickel base heat-resistant alloys. For example, the alloy used for skid rails at a steel mill undergoes regular use at 1,350°C. Thus UMCo50 shows successful results in the application related to heat treatments and furnaces where other alloys could not be used due to their low melting point.
