Quarter-Hard and Stress Relieved (HR01) C19100 Copper
HR01 C19100 copper is C19100 copper in the HR01 (quarter-hard and stress relieved) temper. It has the highest strength compared to the other variants of C19100 copper. The graph bars on the material properties cards below compare HR01 C19100 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.
