Extra-Hard (H06) C19400 Copper
H06 C19400 copper is C19400 copper in the H06 (extra hard) temper. The graph bars on the material properties cards below compare H06 C19400 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.
