Casting is a Process by which alloy Composition can be easily made. Due to daily Advancement in technology the material advancement to improve certain mechanical properties have to make new kinds of alloys. The various processes of Casting Aluminium Alloys were studied. In the cast alloys the basic structure consists of cored dendrites of aluminum solid solution, with a variety of constituents at the grain boundaries or inter-dendritic spaces, forming a brittle, more or less continuous network of eutectics. Wrought products consist of a matrix of aluminum solid solution with the other soluble and insoluble constituents dispersed within it. The coarse aluminium copper alloy was produced by sand mould casting method. Chemical Composition testing is also carried out by using chemical Testing method.
