Spring-Tempered (H08) C42600 Brass
H08 C42600 brass is C42600 brass in the H08 (spring) temper. It has the second highest strength and second lowest ductility compared to the other variants of C42600 brass. The graph bars on the material properties cards below compare H08 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.
