Fully Cold-Worked (H or TD04) C17500 Copper

TD04 C17500 copper is C17500 copper in the TD04 (solution heat treated and cold worked to full-hard) temper. It has the lowest ductility compared to the other variants of C17500 copper. The graph bars on the material properties cards below compare TD04 C17500 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.
