Extra-Spring (H10) C26200 Brass

H10 C26200 brass is C26200 brass in the H10 (extra spring) temper. The graph bars on the material properties cards below compare H10 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.
