Annealed (OS015) C42200 Brass

OS015 C42200 brass is C42200 brass in the OS015 (annealed to 0.015mm grain size) temper. It has the second lowest strength and second highest ductility compared to the other variants of C42200 brass. The graph bars on the material properties cards below compare OS015 C42200 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.
