Galintek - the eutectic of gallium, indium and tin. Such and similar alloys are also known as Galinstan*. It is often used as a thermal compound because of its very good thermal conductivity.
With us you get Galintek with a melting point of 10.7°C. The special feature is that a eutectic has a clearly defined melting point, while near-eutectic alloys have a melting range. The alloy is liquid at room temperature and solidifies into the solid state (liquid-solid phase transition) at a temperature of approximately 0 to -19°C. Furthermore, the composition available from us offers a slightly lower tendency to oxide film Formation.
Eutectic alloys often have different melting points and freezing points. While the melting point is 10.7°C, the metal remains liquid down to a much lower temperature (this depends on crystallization nuclei and can be as low as -19°C). This state is also called supercooled melt.
Furthermore, gallium alloys wet many materials, and the metal also adheres to glass. Therefore, especially the eyes should be protected, as it is very difficult to remove.
- Melting point: 10.7°C
- Freezing temperature: approx. 0 to -19°C
- Boiling temperature: >1300°C
- Density: 6.359g·cm−3
- Surface tension: approx. 600mN/m
- Thermal conductivity: approx. 25W/(m·K)
The packaging sizes 50g and 100g have a dosing tip on the bottle with which the liquid metal can be easily dosed and applied. The bottles are very soft and can therefore be squeezed and emptied very well.
