Soft Annealed (O60) C48600 Brass
O60 C48600 brass is C48600 brass in the O60 (soft annealed) temper. The graph bars on the material properties cards below compare O60 C48600 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.
