nglos324 - brass The phase diagram is shown, and two brasses are identified. Cartridge brass has the composition Cu-30 wt % Zn (green line) and Muntz metal Cu-40 wt % Zn (red line). At room temperature cartridge brass is a single phase substitutional solid solution of zinc in the fcc copper structure. Muntz metal is a two phase (a and g) material at room Copper based alloys - DoITPoMS From the copper-zinc phase diagram we can see the solid solubility of zinc in copper, for concentrations of zinc upto about 30 at.%, at equilibrium the alloy should be of a single phase. Alpha brasses are often seen with a single phase, however this usually arises due to annealing. 09mae324 - PD50 Phase Diagrams Brass · The Copper - Zinc binary phase diagram ( brass ) is another example of a complex phase diagram which shows many invariant reactions. · Two common alloy compositions are shown, Cartridge brass (red) which is Cu-30 wt % Zn, and Muntz metal (green) Cu-40 wt % Zn.
