What does alluminium rusting look like?

Answer 1

Aluminium rusting???? Aluminium metal does NOT rust. 'Rust only applies to Iron.

However, aluminium metal when exposed to oxygen (air), immediately reacts to form alumiunium oxide , which is a white 'powder'.

If you have aluminium pots and pans at home, then the surface that you see/touch is a very fine layer of the impervious aluminium oxide.

NB Many metals react with oxygen to form the oxide, but only Iron forms the oxide known as 'rust'.

Aluminium oxide, is commerically known as 'bauxite'.

Copper oxide is a Black surface on copper metal.

Answer 2

There's no real answer to that. Rust is a non-stoichiometric compound, which is a fancy way of saying that it doesn't have a fixed or simple formula. In addition, it's largely ionic so it doesn't have molecules anyway. Iron(III) oxide, which is rather like dry rust, is a giant ionic lattice containing Fe3+ and O2- ions.

Answer 3

Aluminum does not rust like iron, but it can corrode in the presence of oxygen and moisture. The corrosion on aluminum often appears as a white powdery substance known as aluminum oxide or as pitting on the surface of the metal. This corrosion can weaken the aluminum over time if not properly addressed.

Answer 4

rust looks orangish- reddish and is really nasty and hard to get rid of.

Answer 5

rust is generally gritty and occurrs due to oxidation of steel

Answer 6

It appears on mainly iron, steel, and other things that comtain iron.

Answer 7

Red to reddish brown.

Answer 8

Rusty and rough looking. Probably orange.

Answer 9

Rust is red.
