Ga based liquid metal is processed by non-toxic metals Ga, In, Sn, Zn, silver, etc. Liquid metal at room temperature as a high thermal conductivity, deformable, current and electromagnetic dual control of the flow of metal, is to replace silicone grease as a CPU/GPU heat dissipation is a very ideal material, can also be applied to IGBT and large LED heat dissipation, power battery heat dissipation, can ensure that the interface filling and low thermal resistance.
