Quarter-Hard (H01) C41500 Brass
H01 C41500 brass is C41500 brass in the H01 (quarter hard) temper. It has the second highest ductility compared to the other variants of C41500 brass. The graph bars on the material properties cards below compare H01 C41500 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.
