Extra-Spring (H10) C42200 Brass

H10 C42200 brass is C42200 brass in the H10 (extra spring) temper. It has the highest strength compared to the other variants of C42200 brass. The graph bars on the material properties cards below compare H10 C42200 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.
