AlGa
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 protective oxide layer. A video of gallium metal causing intergrain corrosion and breaking of aluminum can be found here.[1]
Uses
The alloy can be reacted with water to form

Due to AlGa's extreme lack of structural integrity and inability to form a protective oxide layer, gallium metal is considered to be corrosive. If AlGa were to form on an aluminum structure, the aforementioned structure could weaken or collapse. Gallium is subject to strict packaging requirements for transportation by aircraft as it could compromise the integrity of the aluminum hull.[5]
