Quarter-Hard (H01) C46500 Brass
H01 C46500 brass is C46500 brass in the H01 (quarter hard) temper. The graph bars on the material properties cards below compare H01 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.
