Extra-Hard (H06) C26200 Brass

H06 C26200 brass is C26200 brass in the H06 (extra hard) temper. It has the second highest strength compared to the other variants of C26200 brass. The graph bars on the material properties cards below compare H06 C26200 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.
