Spring-Tempered (H08) C10100 Copper
H08 C10100 copper is C10100 copper in the H08 (spring) temper. It has the lowest ductility compared to the other variants of C10100 copper. The graph bars on the material properties cards below compare H08 C10100 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.
