Super-Spring (H14) C66300 Brass

H14 C66300 brass is C66300 brass in the H14 (super spring) temper. It has the highest strength and second lowest ductility compared to the other variants of C66300 brass. The graph bars on the material properties cards below compare H14 C66300 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.
