Annealed (O61) C15000 Copper
O61 C15000 copper is C15000 copper in the O61 (annealed) temper. The graph bars on the material properties cards below compare O61 C15000 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.
