MAR M 247 is a high volume fraction gamma prime alloy (~62%), with good oxidation resistance and good stability due to its high refractory element content. MAR M 247 alloy can be cast into thin wall and complex geometries. Qualified under PWA 1447, PWA 1489, EMS 55447, and DMD 9013-32, it is used for turbine blades and vanes in aerospace and industrial gas turbine applications requiring reliable elevated-temperature performance.
