The wide range of casting alloys helps in selecting the most suitable and cost effective material that meets the requirements of a particular application. Each of these casting alloy has its own physical and mechanical properties. They also have their own casting characteristics, like:

1.Weldability
2.Machinability
3.Corrosion resistance
4.Heat treatment properties

Furthermore, the continuous research on alloying elements often results in the invention and development of more powerful and suitable casting alloys to meet the demands of industry applications. Selecting the proper casting method and the most suitable alloy are two major things that help in achieving optimum cost level for a specific.
