In order to clarify the effect of Zn concentration on the habit planes of α phase in the β´ matrix, an embossing method and SEM-ECP observation were applied to Cu-39.6 mass%Zn alloy and Cu-43.2 mass%Zn alloy. In the both alloys, α phase, which always exists as a pair of plates, had a straight line at the center of the triangular α Phase as one of the feature. For the relatively lower Zn content alloy (Cu-39.6 mass%Zn alloy), the habit plane of α phase in β´ matrix was found near{ 3 17 18}_m plane of the matrix. In this case, four kinds of crystallographically equivalent habit planes, (3 17 18), (3 18 17), (3^^- 17 18) and (3^^- 18 17) existed, and the values of these habit planes were almost equal to those of {5 27 29}_m obtained for Cu-41.7 mass%Zn alloy. For the relatively higher Zn content alloy (Cu-43.2 mass%Zn alloy), the habit plane of α phase in β´ matrix existed near {3 14 14}_m plane of the matrix. Merely two kinds of crystallografically equivalent habit planes, (3 14 14) and (3^^- 14 14) were found in this alloy.
