Heat Treated (HT) C95300 Bronze
Heat treated C95300 bronze is C95300 bronze in the heat treated (HT) condition. The graph bars on the material properties cards below compare heat treated C95300 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.
