Information AboutWood's Metal |
|
Wood's metal, named after American metallurgist , Bendalloy , and Pewtalloy . Bearmetal-158, an alloy marketed by a model train vendor, is considered by some to be another name. Typical applications are as low-melting Solder , low-temperature casting metal, as a high temperature coupling fluid in heat baths, and as a fire-melted valve element in building Sprinkler System s. Medical Gas Cylinders in the UK have a Wood's metal seal which melts in fire, allowing the contents to escape and reducing the risk of explosion. The lead and cadmium components of the alloy makes it toxic. Field's Metal is its non-toxic alternative. Because of its low melting temperature, Wood's metal is useful for repairing antiques. To repair a bent piece made of sheet metal, a die can be cast from a good example, and the low temperature of the alloy makes it unlikely that the original will be harmed by the process. The damaged piece can then be clamped in the die and slowly tightened to form it back into shape. Other low-melting solders and Fusible Alloy s include Rose Metal , Galinstan , NaK , and alloys of Indium and Bismuth . SEE ALSO EXTERNAL LINKS
