Quarter-Hard (H01) C22600 Bronze

H01 C22600 bronze is C22600 bronze in the H01 (quarter hard) temper. It has the lowest strength and highest ductility compared to the other variants of C22600 bronze. The graph bars on the material properties cards below compare H01 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.
