      The structure of complex brass can be calculated based on the "zinc equivalent coefficient" of elements added to brass. Because a small amount of other alloying elements are added to the copper-zinc alloy, the α / (α + β) phase zone in the Cu-Zn state diagram is usually moved to the left or right. Therefore, the structure of special brass is usually equivalent to the structure of ordinary brass that has increased or decreased zinc content. For example, the structure after adding 1% silicon to the Cu-Zn alloy is equivalent to the alloy structure adding 10% zinc to the Cu-Zn alloy. So the "zinc equivalent" of silicon is 10. The "zinc equivalent coefficient" of silicon is the largest, which makes the α / (α + β) phase boundary in the Cu-Zn system move significantly to the copper side, that is, the α phase region is strongly reduced. Nickel's "zinc equivalent coefficient" is a negative value, which expands the alpha phase region.
