Extra-Hard (H06) C19800 Copper

H06 C19800 copper is C19800 copper in the H06 (extra hard) temper. It has the highest strength and lowest ductility compared to the other variants of C19800 copper. The graph bars on the material properties cards below compare H06 C19800 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.
