As Hot Rolled (M20) C10400 Copper

M20 C10400 copper is C10400 copper in the M20 (as hot rolled) condition. It has the highest ductility compared to the other variants of C10400 copper. The graph bars on the material properties cards below compare M20 C10400 copper to: wrought coppers (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.
