Cobalt Welding Alloys

Pura-Weld™ Cobalt Welding Alloys

These cobalt welding, casting and hard facing alloys are for use on cobalt superalloys. Many applications can be found in gas turbines where high temperature strength, resistance to oxidation and wear resistance are required.

Key Points

Cobalt alloys can be used for hardfacing, welding of gas turbine engine blades and hot section components as well as for repair of high or low pressure turbine blades.
