Annealed and Aged (AT or TF00) C18200 Copper
TF00 C18200 copper is C18200 copper in the TF00 (precipitation hardened) temper. The graph bars on the material properties cards below compare TF00 C18200 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.
