Wood's metal is a fusible alloy primarily composed of bismuth, lead, tin, and cadmium, known for its low melting point, which typically ranges around 70°C (158°F). This alloy is notable for its ability to melt easily and solidify quickly, making it useful in applications such as casting and as a heat transfer medium. Wood's metal exhibits good thermal conductivity and is resistant to oxidation, which enhances its stability in various environments. Its unique properties allow it to be used in safety devices, such as fire sprinklers and automatic shut-off systems, where it can melt and trigger a response to heat. However, due to the presence of lead and cadmium, Wood's metal poses health and environmental risks, necessitating careful handling and disposal. The alloy's composition can vary slightly depending on the specific formulation, but its characteristic low melting point and fusibility remain consistent across variations.

<p>Wood's metal is useful as a low-melting solder, low-temperature casting metal, high temperature coupling fluid in heat baths, and as a fire-melted valve element in fire sprinkler systems in buildings. It is also used as a filler when bending thin-walled metal tube. This Thermo Scientific Chemicals b</p>
