Quarter-Hard (H01) C63600 Bronze
H01 C63600 bronze is C63600 bronze in the H01 (quarter hard) temper. It has the highest strength and lowest ductility compared to the other variants of C63600 bronze. The graph bars on the material properties cards below compare H01 C63600 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.
