Extra-Hard (H06) C26000 Brass
H06 C26000 brass is C26000 brass in the H06 (extra hard) temper. The graph bars on the material properties cards below compare H06 C26000 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.
