Recently I produced zinc- and aluminium-gallium alloys. There are two ways to do this with zinc. The first method is to react zinc with an acidic solution of a gallium salt. The gallium produced dissolves in the zinc metal to form the alloy containing a vast majority of zinc. It is highly brittle. Another way is to clean zinc by short immersion in hydrochloric acid and then place galinstan on the zinc. The galinstan will absorb into the zinc, forming an alloy containing a large minority of galinstan. The properties of this high-galinstan zinc alloy have not been determined yet.  Aluminium alloys are made by scratching aluminium and applying a bead of galinstan. The aluminium dissolves in the galinstan as the galinstan dissolves in the aluminium. The protective layer is removed and grayish aluminium oxide growths appear. A low-galinstan aluminium alloy slowly oxidizes and is very structurally unsound. A high-galinstan aluminium alloy is liquid or near liquid and reacts vigorously with water, meanwhile oxidizing rapidly in air. First is aluminium strip with galinstan on it. The aluminium oxide has completely covered the galinstan in a hemispherical shape. The next is aluminium foil with galinstan on it. The aluminium oxide coating has been partially mixed with the galinstan. The third is zinc with galinstan on it. The shiny areas have high galinstan concentration.

yeah thanks for reply,i have also tried but it doesnt reacts with water..its so brittle alloy.

i also tried MgGa alloy .its reacts slowly with water then AlGa alloy.

dose gallium zinc alloy reacts with water as GaAll Alloy?

Zinc is much less reactive than aluminium, so no, it does not react. I've made it and it is brittle but quite similar to normal zinc metal.
