Quater-Hard (H01) C66100 Bronze

H01 C66100 bronze is C66100 bronze in the H01 (quarter hard) temper. It has the second lowest strength and second highest ductility compared to the other variants of C66100 bronze. The graph bars on the material properties cards below compare H01 C66100 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.
