We have worked with NASA in the development and testing of Ultra High Temperature (UHT) Shape Memory Alloys. This actuator features Nickel-Titanium-Palladium (NiTiPd) and Nickel-Titanium-Platinum (NiTiPt). These alloys have a very steep transition temperature in the 150 Celsius to 250 Celsius range, but have maximum strain of roughly 2% (roughly half that of the binary alloys).
