Alloy: Sn 13.3 % Bi 47,4 % Pb 38,62 % 

Melting Temperature: 97°C 

The alloy expands upon solidification due to its high bismuth content. It is cadmium-free, making it less toxic.

Used to create precise impressions and master models due to expansion during cooling.

As temperature-sensitive elements in fire detectors and safety valves.

Soldering using Newton's alloy is acceptable for:

Tinning of low-current wiring lines operating in high-humidity conditions;

• Protective coating of shielding components for radiation safety and radiation protection devices;

• Soldering components of optical devices and instruments;

• Electronic processes for the deposition of nanoparticles from the vapor phase;

• Step soldering of components with variable cross-sections operating at room temperatures.
