3/4-Hard (H03) C41300 Brass
H03 C41300 brass is C41300 brass in the H03 (3/4 hard) temper. The graph bars on the material properties cards below compare H03 C41300 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.
