3/4-Hard (H03) C22600 Bronze
H03 C22600 bronze is C22600 bronze in the H03 (3/4 hard) temper. The graph bars on the material properties cards below compare H03 C22600 bronze to: wrought bronzes (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.
