One advantage of the investment casting process is that it can utilize both ferrous and nonferrous alloys to produce specialized parts. The basic difference is that ferrous alloys contain some amount of iron, while nonferrous alloys do not. There are other differences, but that’s a good start. Ferrous alloys include Stainless Steel, Carbon Steel, Mild Steel, Cast Iron and Wrought Iron. They are used for an wide variety of applications, from general purposes to cutting tools, surgical instruments, engine blocks, manhole covers, decorative pieces and much more. Nonferrous alloys include Aluminum, Brass, Copper, Lead and Silver. They can be used to produce ultra-lightweight components, heat and electrical conductors, ornamental, solders, roofing, batteries, pipes and many others.
