High strength across wide temperatures
An aged copper alloy that offers an excellent combination of strength and ductility at room temperature and 300 °C, while overcoming intermediate-temperature embrittlement at 500 °C under high strain rates.

Excellent strength–ductility balance at room temperature and 300 °C
Severe ductility loss at 500 °C, indicating intermediate temperature embrittlement
Improved ductility at 500 °C under high strain rates by suppressing grain-boundary damage
Precipitation (Orowan bypassing) and dislocation hardening dominated at all temperatures
