CarTech CTX-909 alloy is a high-strength, precipitation hardenable superalloy which exhibits a low and relatively constant coefficient of thermal expansion over a broad temperature range, high hot hardness and good thermal fatigue resistance.

This alloy offers significant improvement over CarTech CTX-1 alloy and CarTech CTX-3 alloy due to its excellent combination of tensile properties and stress rupture strength in the recrystallized condition combined with the use of common age hardening treatments.

CarTech CTX-909 alloy is weldable, brazable, and can be chromium plated.

Applications:
CarTech CTX-909 alloy has been used in compressor and exhaust casings, seals and other gas turbine engine components. It also has excellent characteristics . . . and could be considered for . . . applications such as:

Ordnance hardware
Gauge blocks
Rocket engine thrust chambers
Steam turbine blades
Springs
Die-casting dies

This alloy could also be considered for use in applications requiring resistance to thermal fatigue in non-corrosive environments.
