Predominant analysis specimen has been fundamentally superimposed from Aluminum beside of Zinc structure. EDX pattern of present uses specimens; where white Al phase and dark Zn phase has been represented in Figure (17). The Scanning Electron Microscope morphology for two specimens is illustrated in Figure (18); within Figure (18) a); is Al-8Zn, where Al with white phase in prevalent phase while Zn is minority dark phase; while in b) is Al-85Zn binary alloy where Al with white phase in minority phase while Zn is gray.
