Quarter-Hard (H01) C35600 Brass

H01 C35600 brass is C35600 brass in the H01 (quarter hard) temper. It has the second lowest strength compared to the other variants of C35600 brass. The graph bars on the material properties cards below compare H01 C35600 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.
