Aluminum-gallium amalgam

The gallium doesn’t react with water, the metal drops out of solution. The aluminum metal reacts vigorously with water producing aluminum oxide according to this formula:

2Al + 3H2O → 3H2 ↑ + Al2O3,
AlGa + 3H2O → AlO3 + 3H2 ↑ + Ga ↓

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 aluminium from forming a protective oxide layer.

Uses:
The alloy can be reacted with water to form hydrogen gas, aluminium oxide and gallium metal.

Safety concerns:
Due to AlGa extreme lack of structural integrity and ability 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 illegal to transport on aircraft as it could compromise the integrity of the aluminium hull.

This reaction splits the oxygen and hydrogen contained in water, releasing hydrogen in the process. The gallium is critical to the process because it hinders the formation of a skin normally created on aluminum's surface after oxidation. This skin usually prevents oxygen from reacting with aluminum, acting as a barrier. Preventing the skin's formation allows the reaction to continue until all of the aluminum is used.

Bro amazing, I will give it a try... Can I use some Part of your videos? Cause I do not have access to all the reagents.

now let's reduce some compounds...

Wow, i never knew that, can you add more aluminium to the leftover gallium to produce more hydrogen and run a car, it would be cool if you can just top up a car on aluminium foil and water ?
