Construction of a Eutectic Phase Diagram This phase is referred to as "alpha brass" and includes pure copper; we can think of copper as an a-brass with zero zinc content. Yet, if the 38% zinc solubility limit is exceeded, a second Cu-Zn phase forms which can accommodate additional zinc by re-arranging its structure to a body-centered-cubic structure called "beta brass."
