Half-Hard (H02) C46500 Brass
H02 C46500 brass is C46500 brass in the H02 (half hard) temper. It has the second highest strength and second lowest ductility compared to the other variants of C46500 brass. The graph bars on the material properties cards below compare H02 C46500 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.
