Annealed (A or TB00) C17200 Copper
TB00 C17200 copper is C17200 copper in the TB00 (solution heat treated) temper. It has the lowest strength and highest ductility compared to the other variants of C17200 copper. The graph bars on the material properties cards below compare TB00 C17200 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.
