This diagram helps to explain the solidification behavior, phase transformations, and mechanical properties of copper-zinc alloys. The phase diagram consists of a composition axis and a temperature axis. The composition axis represents the ratio of copper to zinc in the alloy, ranging from pure copper ( copper) to pure zinc ( zinc).
