Extra-Spring (H10) C15500 Copper

H10 C15500 copper is C15500 copper in the H10 (extra spring) temper. The graph bars on the material properties cards below compare H10 C15500 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.
