Description

Bismuth is a brittle, high-density, low melting point metal that has few uses in its pure state. When alloyed with other metals, on the other hand, it can be custom tailored for different applications such as fire alarms, solders and more. One of the most noticeable properties is that solid bismuth is lighter than the liquid (similar to ice and water), which means that when it solidifies it expands. This property has been classically used in type casting for printing presses, because the expanding metal fills every small crevice in the mould to produce perfectly shaped letters or numbers.
