Melt and pour these alloys into molds to create metal parts and prototypes.

Bismuth and indium alloys expand slightly as they solidify, pushing into the crevices of a mold to produce detailed replicas. These alloys are useful for repairing dies, creating fusible links, and holding delicate parts for machining. Indium alloys have a low melting temperature so they can be cast in molds made from glass, quartz, mica, and ceramic.

Lead can be used for caulking, castings, and hot-dipped coatings.

Lead-base babbitt is a soft alloy. Use it to cast light-load bearings. It has superior antifriction properties.

Lead hammer metal is commonly used to cast nonmarring hammer heads. This ductile material is hard and won't chip.

Tin-base babbitt is used to cast bearings for high-speed, high-wear applications and can withstand heavy, sustained loads. It has a higher melting temperature than lead-base babbitt.

Zinc alloy is nonshrinking and corrosion resistant. Parts cast from this material are easy to machine.

Silicon-bronze alloy is often used to cast gears, propellers, bells, and plaques. It renders an excellent surface finish.
