Hard-Drawn (H80) C37100 Brass

H80 C37100 brass is C37100 brass in the H80 (hard drawn) temper. The graph bars on the material properties cards below compare H80 C37100 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.
