As Forged and Air Cooled (M10) C67600 Bronze

M10 C67600 bronze is C67600 bronze in the M10 (as forged and air cooled) condition. The graph bars on the material properties cards below compare M10 C67600 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.
