Features:
Mar-M509 cobalt alloys have various high temperature applications for the aerospace industry.
Application:
Mar-M509 is a cobalt-based alloy that may be used as a replacement for nickel-based alloys common in gas turbine engines due to the extreme thermal and fluid aero environment. The unique carbide and cellular structure of Mar-M509 create stable intermetallic phases that lead to Mar-M509's superior high temperature creep and corrosion resistance.
