Gallium infiltration of aluminum
WebJun 5, 2015 · As you state, it forms an amalgam, just as mercury does. @Jon Custer's explanation is correct, and furthermore, the alloy does not form a protective oxide, so the aluminum oxidizes to $\ce{Al2O3}$ and quickly crumbles.This happens even faster with an Hg-Ga alloy!. BTW, gallium should be safe enough, though expensive, but I would not … WebWhen the liquid gallium contacts the solid aluminum they combine and form an alloy much softer and brittle than the aluminum alone. This happens especially along the grain boundaries of the aluminum alloy because gallium is very good at wetting the aluminum surface. The similar thing happens with mercury and various metals.

AlGa (Aluminum-Gallium) is a degenerate alloy that results from liquid gallium infiltrating the crystal structure of aluminium metal. The resulting alloy is very weak and brittle, being broken under the most minute pressure. The alloy is also chemically weaker, as the gallium inhibits the aluminum from forming a … See more The alloy can be reacted with water to form hydrogen gas, aluminum oxide and gallium metal. Normally, aluminum does not react with water, since it instantly reacts in air to form a passivation layer of aluminum oxide. … See more Due to AlGa's extreme lack of structural integrity and inability to form a protective oxide layer, gallium metal is considered to be corrosive.
