1. GaInSn is a commercial liquid metal alloy whose composition is taken from a family of eutectic alloys mainly consisting

    of gallium, indium, and tin. Such eutectic alloys are liquids at room temperature, typically melting at −19 °C (−2 °F).



2. Santech Materials specializes in producing Galinstan with typical proportion (Ga 68.5%, In 21.5%, Sn 10%), or GaIn,

    InSn, GaSn and Copper Indium Gallium Selenide (CIGS) can be customized.

Gallium Indium Tin Alloy used as thermal interface for computer hardware cooling solutions since its excellent Thermal and Electrical Conductivity. Alloy systems that are liquid at room temperature have a high degree of thermal conductivity far superior to ordinary nonmetallic liquids. This results in the use of these materials for specific heat conducting and/or dissipation applications. Other advantages of these liquid alloy systems are their inherent high densities and electrical conductivities.
