Full-Hard and Stress Relieved (HR04) C19000 Copper
HR04 C19000 copper is C19000 copper in the HR04 (full-hard and stress relieved) temper. The graph bars on the material properties cards below compare HR04 C19000 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.
