As Forged and Quenched (M11) C14700 Copper
M11 C14700 copper is C14700 copper in the M11 (as forged and quenched) condition. The graph bars on the material properties cards below compare M11 C14700 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.
