Full-Hard (H04) C14700 Copper
H04 C14700 copper is C14700 copper in the H04 (full hard) temper. It has the highest strength compared to the other variants of C14700 copper. The graph bars on the material properties cards below compare H04 C14700 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.
