Half-Hard (H02) C19500 Copper
H02 C19500 copper is C19500 copper in the H02 (half hard) temper. The graph bars on the material properties cards below compare H02 C19500 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.
