Soft Annealed (O60) C36200 Brass
O60 C36200 brass is C36200 brass in the O60 (soft annealed) temper. It has the lowest strength and highest ductility compared to the other variants of C36200 brass. The graph bars on the material properties cards below compare O60 C36200 brass to: wrought brasses (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.
