Full-Hard and Stress Relieved (HR04) C66200 Brass

HR04 C66200 brass is C66200 brass in the HR04 (full-hard and stress relieved) temper. The graph bars on the material properties cards below compare HR04 C66200 brass to: wrought brasses (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.
