CarTech CTX-3 alloy is a high strength, precipitation hardenable superalloy which exhibits a low coefficient of thermal expansion over a broad temperature range. This alloy also possesses high hot hardness and good thermal fatigue resistance.

CarTech CTX-3 alloy is weldable, brazable, and can be chromium plated.

This material offers significant improvement in notched stress-rupture strength over CarTech CTX-1 alloy. Retained hot-cold work is not required for good stress rupture properties and, in contrast to CarTech CTX-1 alloy, is not affected by stress orientation.

Applications:
CarTech CTX-3 alloy has been used for compressor and exhaust casings, seals and other gas turbine engine components. It also has excellent characteristics . . . and should be considered . . . for applications such as:

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

In addition, this material could be considered for use in applications requiring resistance to thermal fatigue in noncorrosive environments.
