Full-Hard (H04) C14500 Copper
H04 C14500 copper is C14500 copper in the H04 (full hard) temper. It has the highest strength and lowest ductility compared to the other variants of C14500 copper. The graph bars on the material properties cards below compare H04 C14500 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.
