Spring-Tempered (H08) C19010 Copper
H08 C19010 copper is C19010 copper in the H08 (spring) temper. It has the second highest strength and lowest ductility compared to the other variants of C19010 copper. The graph bars on the material properties cards below compare H08 C19010 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.
