As Hot Extruded (M30) C46200 Brass

M30 C46200 brass is C46200 brass in the M30 (as hot extruded) condition. The graph bars on the material properties cards below compare M30 C46200 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.
