Hard Drawn (H80) C10800 Copper

H80 C10800 copper is C10800 copper in the H80 (hard drawn) temper. It has the second highest strength and second lowest ductility compared to the other variants of C10800 copper. The graph bars on the material properties cards below compare H80 C10800 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.
