Full-Hard (H04) C49300 Brass
H04 C49300 brass is C49300 brass in the H04 (full hard) temper. It has the highest strength and lowest ductility compared to the other variants of C49300 brass. The graph bars on the material properties cards below compare H04 C49300 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.
