Liquid metal will wet to most metallic surfaces. Specifically though, room-temperature liquid metal can be very reactive with certain metals. Liquid metal can dissolve most metals; however, at moderate temperatures, only some are slightly soluble, such as sodium, potassium, gold, magnesium, lead, nickel and mercury. Gallium is corrosive to all metals except tungsten and tantalum, which have a high resistance to corrosion, more so than niobium, titanium and molybdenum. Similar to indium, gallium and gallium-containing alloys have the ability to wet to many non-metallic surfaces such as glass and quartz. Gently rubbing the alloy into the surface may help induce wetting. However,
Liquid metal can move in free space and in various structural channels; surprisingly, it can also make its own deformation adjustment according to the width of the path along the path. The dynamic mechanism comes from two aspects. According to Rebinder's effect , liquid metal alloy EGaIn or Galinstan would penetrate into aluminum, destroying the oxide skin on Al surface and leading to the activation of Al. In NaOH solution, Al is the cathode and liquid metal works as the anode. the dissolution of Al on the cathode renders Al to lose electrons, Under the equilibrium state, gallium reacts with the alkali
