Fully Cold-Worked and Aged (HT or TH04) C17510 Copper

TH04 C17510 copper is C17510 copper in the TH04 (full-hard and precipitation heat treated) temper. It has the highest strength and lowest ductility compared to the other variants of C17510 copper. The graph bars on the material properties cards below compare TH04 C17510 copper to: wrought coppers (top), all copper alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
