Spring-Tempered (H08) C41300 Brass

H08 C41300 brass is C41300 brass in the H08 (spring) temper. It has the highest strength and second lowest ductility compared to the other variants of C41300 brass. The graph bars on the material properties cards below compare H08 C41300 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.
