Define the following materials in terms of their properties and give an example each of their application. a. Stainless steel b. Brass c. Cast iron 3  P ROCESSINGOFMETAL - CASTING 4  Most metals are first melted in a furnace.  Alloying is done if required.  Large ingots are then cast.  Sheets and plates are then produced from ingots by rolling (wrought alloy products).  Channels and other shapes are produced by extrusion.  Some small parts can be cast as final product. Example :-Automobile Piston.
