Annealed (OS050) C16200 Copper
OS050 C16200 copper is C16200 copper in the OS050 (annealed to 0.050mm grain size) temper. It has the lowest strength and highest ductility compared to the other variants of C16200 copper. The graph bars on the material properties cards below compare OS050 C16200 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.
