One advantage of investment casting is the ability to cast parts using both nonferrous and ferrous alloys, which makes it appropriate for a wide range of specialized parts. The difference between the two types of metal is essentially that ferrous alloys contain some iron, while nonferrous alloys do not contain any. Ferrous alloys include Carbon Steel, Mild Steel, Stainless Steel, Cast Iron and Wrought Iron. It is used for numerous applications, including cutting tools, engine blocks, decorative pieces, manhole covers, surgical instruments, general purposes and many others. Nonferrous alloys include Aluminum, Brass, Copper, Lead and Silver. They are utilized for ultra-lightweight components, heat and electrical conductors, batteries solders, ornamental, roofing, pipes and much more.
