Extra-Hard (H06) C12200 Copper
H06 C12200 copper is C12200 copper in the H06 (extra hard) temper. It has the second lowest ductility compared to the other variants of C12200 copper. The graph bars on the material properties cards below compare H06 C12200 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.
