Based on various studies, the most favorable composition of alloys used in for casting applications, exhibits improved mechanical and physical characteristics. Since the casting alloys show excellent mechanical and physical feature, however, it is difficult to make out whether these casting alloys could be used for die casting applications effortlessly.

The physical and metallurgical features forming the nature of casting alloy, during process of casting are known as casting characteristics of an alloy. The alloy characteristics that are influential in the process of die-casting are the affinities of the alloy towards the process of die-soldering, procedure of hot-tearing, development of sludge formation, the fluidity nature of casting alloys, machinability of the components, formation of pours and macro segregation.

Castability of Alloys
Properties of alloys that influence the nature of the process of casting are defined as ?Castabilty ? of an alloy. Being cast with preferred features, an alloy must consist of multiple varied characteristics. In some cases, during the process of production of casting, the alloy’s performance following to metal casting is defined as a metal casting characteristic like the alloys easiness of machining, fusing the jobs, and process of anodization. A varied casting process involves the casting alloy to possess varied casting characteristics.

A specific feature of the alloy may be of importance only to limited casting process or it possesses varied level of significance in different kinds of casting processes. For example, a good soldering resistance influences the process of pressure die-casting, while that quality is not significant in sand casting process. This study is based primarily on those metal casting features that are specifically essential to the process of pressure die-casting, namely, tendency of forming sludge, die soldering capability, fluidity of the alloy, and machinability.
