Spring-Tempered (H08) C26200 Brass
H08 C26200 brass is C26200 brass in the H08 (spring) temper. It has the highest strength compared to the other variants of C26200 brass. The graph bars on the material properties cards below compare H08 C26200 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.
