As Hot Rolled (M20) C23000 Brass
M20 C23000 brass is C23000 brass in the M20 (as hot rolled) condition. It has the second lowest strength compared to the other variants of C23000 brass. The graph bars on the material properties cards below compare M20 C23000 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.
