1/8-Hard (H00) C12900 Copper

H00 C12900 copper is C12900 copper in the H00 (1/8 hard) temper. The graph bars on the material properties cards below compare H00 C12900 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.
