Half-Hard (H02) C43500 Brass

H02 C43500 brass is C43500 brass in the H02 (half hard) temper. The graph bars on the material properties cards below compare H02 C43500 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.
