Annealed (OS025) C14200 Copper
OS025 C14200 copper is C14200 copper in the OS025 (annealed to 0.025mm grain size) temper. It has the second lowest strength compared to the other variants of C14200 copper. The graph bars on the material properties cards below compare OS025 C14200 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.
