Annealed (A or TB00) C17300 Copper

TB00 C17300 copper is C17300 copper in the TB00 (solution heat treated) temper. It has the lowest strength and highest ductility compared to the other variants of C17300 copper. The graph bars on the material properties cards below compare TB00 C17300 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.
