Quarter-Hard (H01) C15500 Copper
H01 C15500 copper is C15500 copper in the H01 (quarter hard) temper. It has the second lowest strength and second highest ductility compared to the other variants of C15500 copper. The graph bars on the material properties cards below compare H01 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.
