Half-Hard (H02) C14700 Copper

H02 C14700 copper is C14700 copper in the H02 (half hard) temper. It has the lowest ductility compared to the other variants of C14700 copper. The graph bars on the material properties cards below compare H02 C14700 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.
