According to the mineral network, gallium indium tin alloy (Galinstan, Ga 68.5%, In2 1.5%, Sn 10%) is a liquid metal alloy. Gallium indium (tin) alloy, as a new non-toxic and pollution-free liquid metal, is widely used as a substitute for mercury in radiators and thermometers because of its non-toxicity, pollution-free and low melting point. However, due to the high manufacturing cost, gallium indium (tin) alloy is not widely used at present, and only a few people abroad have made and studied this alloy.

Gallium-based alloys are used more and more, which can replace toxic mercury. The evaporation pressure of mercury at room temperature is very high. These alloys reduce toxicity, and their evaporation pressure is lower than that of mercury. Excellent electrical conductivity and thermal conductivity, the thermal conductivity of alloys that are liquid at room temperature is very high, far higher than that of nonmetallic liquids. Therefore, these materials are used for heat conduction and/or heat dissipation. Other advantages of these liquid alloys are high density and high conductivity. Wettability of metal surface and nonmetal surface. As long as the oxides on the substrate surface are completely removed, these alloys can penetrate into most metal surfaces.
