Annealed (OS050) C12900 Copper

OS050 C12900 copper is C12900 copper in the OS050 (annealed to 0.050mm grain size) temper. The graph bars on the material properties cards below compare OS050 C12900 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.
