Quarter-Hard (H01) C65100 Bronze

H01 C65100 bronze is C65100 bronze in the H01 (quarter hard) temper. The graph bars on the material properties cards below compare H01 C65100 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.
