How is bismuth used in fire extinguishers?
When bismuth is combined with other metals such as lead, tin, iron and cadmium, it forms alloys with low melting points that can be used in fire detectors and extinguishers.
How is bismuth used in fire sprinklers?
But Wood’s metal, an alloy of bismuth containing 12% cadmium, has a remarkably low melting point of 70°C. This makes it ideal for use in automatic fire sprinkler systems. When hot gases from a fire enter the head of the sprinkler, the melting metal releases a valve that allows water to gush out.
