Rose's metal, also called Rose metal or Rose's alloy is a fusible alloy with a low melting point.
Contents
Composition
Rose's metal consists of 50% bismuth, 25–28% lead and 22–25% tin by weight. Its melting point is between 94-98 °C (201-208 °F).
Properties
Rose's metal is a relative dense silvery-gray alloy. The alloy does not contract on cooling.
Availability
Rose's metal is sold by various chemical and metallurgical suppliers.
Preparation
Rose's metal can be made by melting bismuth, lead and tin in the respective ratios.
Uses
- Heating bath
- Solder
- Malleable filling to prevent tubes and pipes from crimping when bent
Safety
The alloy contains lead, which is toxic.
