As Forged and Air Cooled (M10) C63200 Bronze
M10 C63200 bronze is C63200 bronze in the M10 (as forged and air cooled) condition. It has the lowest strength compared to the other variants of C63200 bronze. The graph bars on the material properties cards below compare M10 C63200 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.
