Hard Drawn (H80) C43500 Brass

H80 C43500 brass is C43500 brass in the H80 (hard drawn) temper. It has the second highest strength and second lowest ductility compared to the other variants of C43500 brass. The graph bars on the material properties cards below compare H80 C43500 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.
