As Hot Extruded (M30) C64200 Bronze

M30 C64200 bronze is C64200 bronze in the M30 (as hot extruded) condition. It has the second lowest strength compared to the other variants of C64200 bronze. The graph bars on the material properties cards below compare M30 C64200 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.
