Sand casting is applicable to all metals other than exotics such as mercury and gallium. It is particularly well suited to high-cost/high-temperature materials such as titanium and nickel. It is most practical in the manufacture of relatively low cost and larger parts, often including some post machining to impose dimensional precision in the areas that require it. Metals commonly sand cast are: aluminum alloys, bronzes (gunmetal, nickel-aluminum bronze, etc.), steel, iron (nodular (gray), white, ductile, and malleable), brass, and stainless steels.
