Soft Annealed (O60) C19200 Copper
O60 C19200 copper is C19200 copper in the O60 (soft annealed) temper. It has the lowest strength and second highest ductility compared to the other variants of C19200 copper. The graph bars on the material properties cards below compare O60 C19200 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.
