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.
