Sep 26, 2018.Rusting is a specialized form of corrosion that only iron and steel go through. Rust is when the iron oxidizes and flakes off. It accelerated by moisture. Flaking exposes fresh metal beneath, which in turn oxidizes and flakes. Aluminum oxidation happens faster than that of steel, because aluminum has a really strong affinity for oxygen.

Look for a product designed for aluminum use to avoid damaging the metal. Make sure to smooth the coating out if it pools in any spots.
An aluminium alloy contains vanadium as an alloying element. The vanadium is preferably at a concentration in the range from 0.02% to 0.4% by weight and imparts corrosion-resistance to the alloy, particularly when it is used as a core alloy in a vacuum brazing sheet. Further corrosion resistance is also achieved by processing the alloy or brazing sheet in such a manner that the
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13.Aluminium has a density lower than those of other common metals, at approximay one third that of steel.It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to
