Extra-Spring (H10) C11300 Copper

H10 C11300 copper is C11300 copper in the H10 (extra spring) temper. It has the highest strength compared to the other variants of C11300 copper. The graph bars on the material properties cards below compare H10 C11300 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.
