Casting Metals

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

Bismuth

Image of Product. Front orientation. Casting Metals.

Bismuth 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 Alloy

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. They also have a low melting temperature so they can be cast in molds made from glass, quartz, mica, and ceramic.
