TM00 Mill Hardened C17000 Copper
TM00 C17000 copper is C17000 copper in the TM00 (mill annealed) temper. It has the second highest ductility compared to the other variants of C17000 copper. The graph bars on the material properties cards below compare TM00 C17000 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.
