Rose's metal consists of Bismuth, Lead and Tin. Its melting point is between 94oC and 98oC. The alloy
does not contract on cooling
Rose's metal is typically used as a solder, but has also been used to secure cast iron railings and balusters
in stone steps and bases. Rose's metal can also be used for the bending of tubes, and as a heat transfer
medium in constant temperature baths.
The alloy was discovered by the German chemist Valentin Rose the elder.
