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

Conductive Liquid Gallium
A safe alternative to mercury in thermometers and thermostats, gallium transfers heat and electricity without toxic vapor that can be inhaled. Also known as Galinstan. Its low melting point means it's liquid at room temperature. When used next to parts that generate concentrated heat, it dissipates the heat quickly, making it good thermal interface material. It also allows electricity to pass throughout it, so it's often used in switches and electronics that must bend and flex.
Gallium clings to both metallic and nonmetallic surfaces such as glass and quartz. However, it eats away at most metal when used at high temperatures and dissolves aluminum even at ambient temperatures.
When choosing gallium, keep in mind its composition. The higher the gallium and indium content, the better it is at transferring heat. Gallium with tin reduces the melting point, but also decreases how well it transfers heat.
