Annealed (OS015) C42600 Brass
OS015 C42600 brass is C42600 brass in the OS015 (annealed to 0.015mm grain size) temper. It has the lowest strength and highest ductility compared to the other variants of C42600 brass. The graph bars on the material properties cards below compare OS015 C42600 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.
