Soft Annealed (O60) C61000 Bronze

O60 C61000 bronze is C61000 bronze in the O60 (soft annealed) temper. The graph bars on the material properties cards below compare O60 C61000 bronze to: wrought bronzes (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.
