Application
Woods alloy serves multiple purposes due to its low melting point. It is widely used as a solder for joining materials and as a casting metal for applications requiring low temperatures. In heat baths, Woods alloy functions as a high-temperature coupling fluid. Additionally, it acts as a critical safety component in fire sprinkler systems, melting to activate valves during a fire. The alloy is also employed as a filler for bending thin-walled metal tubes. However, caution is advised, as it can expand upon cooling and resolidification, potentially damaging glass containers when used as a bath liquid.
