Investment casting is exceptionally versatile, accommodating almost any metal alloy that can be melted and poured into a ceramic shell. The best and most frequently utilized metals include stainless steel grades for corrosion resistance, carbon and low-alloy steels for structural strength, aluminum alloys for lightweight aerospace and automotive applications, cobalt and nickel-based superalloys for high-temperature turbine components, and copper-based brass and bronze alloys for marine and decorative hardware.
