aluminium is a pure metal element and a fairly reactive one at that therefor is products are mostly compunds of itself and other elements. event the utensils that are said to be made of aluminium are actually composed of aluminium oxide owing to the oxidation of the metal by the oxygen in the atmosphere.

If you mean chemical products then the essential difference is a change of oxidation state from 0 to +3. If you mean materials made from aluminium, such as sheet, plate, extrusions etc. then, apart from a shape change, there is the spontaneous formation of an alumina (aluminium oxide) coating on the surface of any fresh aluminium metal surfaces. If the alumimium product has been anodised then it will have a porous oxide coating that will contain other elements from the anodising bath.

Aluminium is the pure elemental metal.

When it is chemically combined with other elements it forms compounds of other substances.

e.g. Aluminium + hydrochloric acid will give Aluminium Chloride.

Aluminium Oxide is formed from Aluminium and Oxygen ..etc.
