203 to 239 ºF (95 to 119 ºC) Low Melting Point 50% Bismuth Rose Metal Alloys

This is Bismuth based non-eutectic alloy which does not contract upon cooling. It is mainly used as a solder but also as a heat transfer medium. Another application for this material is to serve as a valve element in automatic fire sprinklers. The valve, having a low melting point, melts in fire and provides water to stop the fire from spreading.
