I wish to use galvanized screws tru aluminum roof OR Stainless screws tru aluminum roof . Any chemical reaction ?
Not very much unless it is also mixed with water and subjected to high temperature and pressure to prevent the water boiling. This reaction is used as part of a method for extracting aluminum from bauxite ore. At normal temperatures and pressures, aluminum oxide will dissolve slowly in sodium hydroxide solution to form various complex sodium aluminum hydroxides.
6H3O+ + 2Al --> 2Al3+ + 3H2 + 6H2O[Chloride ions (Cl -) are left out of equation, don't take part in reaction: 'tribune' ions].
The redox reaction is split into its oxidation part and it’s reduction part
Aluminum
Yes, a neutralization reaction always involves an acid and a base.
No.
Extruded aluminum is aluminum that is melted down and extruded, pushed through a certain 2d shaped hole. This can result in square tube, rectangular tube, an L shaped extrude, and an infinite array of other shapes. Powder coated aluminum is aluminum that could be extruded aluminum, that is cleaned, coated with a colored plastic powder, and then baked so that the plastic powder melts and forms a smooth, nice and even coat of colored plastic over the part. This is basically painting the part. Anodized aluminum is aluminum, again this could be extruded aluminum, but it couldn't be powder coated aluminum, that is put in a chemical solution, possibly sulfuric acid, and then a current is run through the aluminum. This causes a reaction to occur where a layer of aluminum oxide gathers on the surface of the part. The processes is then stop and the part can be colored if desired. Anodozing aluminum gives the part better corrosive resistance and makes the surface tougher and harder than it would have been if it had not been anodized. It does add thickness to the part which can be a downside, but it also is lighter than a powder coat if a paint job is desired.
The two wings of the airplane are made of aluminum.

I believe the galvanize process happens as the wire is wound onto gargantuan spools but the important part is... paperclips are typically made of galvanized steel wire.

Neither. Aluminum is an element. As such it can form compounds or be a part of mixtures.
No, aluminum is an element. A common form of sand is silicon dioxide, a compound of two elements neither of which is aluminum.
galvanised material may flake off and set into moving part
