Hard Drawn (H80) C14200 Copper
H80 C14200 copper is C14200 copper in the H80 (hard drawn) temper. It has the highest strength and lowest ductility compared to the other variants of C14200 copper. The graph bars on the material properties cards below compare H80 C14200 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.
