As Cast C99600 Bronze
As-cast C99600 bronze is C99600 bronze in the as-fabricated (no temper or treatment) condition. The graph bars on the material properties cards below compare as-cast C99600 bronze to: cast bronzes (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.
