Precision Investment Casting materials are quite plentiful. Typically, all ferrous and non-ferrous materials can be used. Carbon, tool and alloy steels and many grades of stainless steel are some of the ferrous materials commonly investment cast. Non-ferrous materials include most aluminum and copper-based substances, among others. Heat-resistant alloys can be investment cast for high-temperature applications. The precision  investment cast process allows the switching back and forth between metals (ferrous or non-ferrous) within the ceramic shell molds. Selecting the right combination of alloys will provide the highest corrosion resistance.
