Effects of Alloying on Aluminium-Silicon Alloys – A Review

Abstract

Abstract Some of the factors in which the mechanical, physical and chemical properties of aluminium alloys hinge on are composition and microstructure. The inclusion of specific alloying elements to aluminium in its pure form has been proven to considerably improve its properties and usefulness. Hence, aluminium is substituted with alloys which consist of one or more alloying elements or impurities for applications where it is demanded. Aluminium, as well as its alloys, offers an outstanding combination of properties making it stand out amongst the most adaptable, cost-effective, and appealing metallic materials for a wide scope of employments —from delicate materials like wrapping foil to the most severe engineering applications. Besides steels, aluminium based alloys are most favoured for applications as structural materials.
