The solid α phase is expected to begin to form below 571 C, and due to the very low solubility of silicon in the aluminum chlorofluorocarbon (CFC) structure, formation of Al FCC is expected. The separation of silicon from the α phase will also form the AlFeSi phase, which will coexist with the α phase, Al FCC , and silicon from approximately 558–519 °C.
