Hot Rolled and Annealed (O25) C11300 Copper
O25 C11300 copper is C11300 copper in the O25 (hot rolled and annealed) condition. It has the second highest ductility compared to the other variants of C11300 copper. The graph bars on the material properties cards below compare O25 C11300 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.
