Full-Hard (H04) C18700 Copper

H04 C18700 copper is C18700 copper in the H04 (full hard) temper. The graph bars on the material properties cards below compare H04 C18700 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.
