Alloys that melt at low temperature (around 100°C). They have a number of uses, including constant-temperature baths, pipe bending, and automatic sprinklers to provide a spray of water to prevent fires from spreading. Fusible alloys are usually eutectic mixtures of bismuth, lead, tin, and cadmium. Wood’s metal, Rose’s metal, and Lipowitz’s alloy are examples of alloys that melt in the range 70–100°C.
