  • 12.5% Cd (cadmium)
  • 12.5% Sn (tin)

and is toxic (poisonous).

Properties:

  • Density: 9.60 g / cm³
  • Melting point: 70 ° C


Without cadmium, in the composition 50% Bi - 25% Pb - 25% Sn, the alloy is called Roses Metall and melts at 98 ° C.

use

Wood's metal is used, for example, as a safety fuse for sprinkler systems, in melting core casting and as a filling for bending thin-walled metal pipes. In the past, it was also used in anatomy as a solidifying mass for injection preparations.
