Extra-Spring (H10) C41500 Brass
H10 C41500 brass is C41500 brass in the H10 (extra spring) temper. It has the lowest ductility compared to the other variants of C41500 brass. The graph bars on the material properties cards below compare H10 C41500 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.
