Annealed (OS015) C15100 Copper
OS015 C15100 copper is C15100 copper in the OS015 (annealed to 0.015mm grain size) temper. It has the lowest strength and highest ductility compared to the other variants of C15100 copper. The graph bars on the material properties cards below compare OS015 C15100 copper to: wrought coppers (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.
