More info

Gallium indium eutectic alloy (EGaIn) is a eutectic alloy formed by smelting gallium and metal at high temperatures. It is a highly conductive liquid metal. Gallium indium alloy is liquid at room temperature and also becomes a liquid metal. The proportion of gallium indium alloy can be customized, and it is produced under the protection of nitrogen to prevent oxidation and pollution. The conventional gallium-indium alloy ratio is Ga: In=75.5:24.5 by weight, Ga: In=74.5:25.5 by weight, Ga: In=80:20 by weight, etc.
