Full-Hard (H04) C42600 Brass
H04 C42600 brass is C42600 brass in the H04 (full hard) temper. The graph bars on the material properties cards below compare H04 C42600 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.
