WebAug 13, 2024 · Aluminum has a very high affinity to oxygen. When a new aluminum surface is exposed in the presence of air or any other oxidizing agent, it quickly develops a thin, hard film of aluminum oxide (or hydrated oxide in non-stagnant water). This aluminum oxidation is precisely what makes aluminum so corrosion-resistant. http://bolasystems.com/help-advice/galvanic-corrosion-what-it-is-and-how-to-fight-it
