Aluminum should oxidize essentially instantly.
- lukevp 6mo agoAnodizing and oxidation are 2 totally different things.
- Brian_K_White 6mo agoanodizing is literally oxidizing
- nikisweeting 6mo agoYes but anodization implies thickness around ~5–25 micrometers (µm) for aluminum. The natural oxide coating is ~2-5 nanometers (1,000–5,000× less thick).
- themafia 6mo agoTrue; however, this is an aluminium alloy. These typically have lower corrosion resistance and are most commonly anodized because of it. The applied layer is typically 3 to 5x thicker than that formed by pure aluminium oxidization.
- nikisweeting 6mo agoYou're off by at least 3 orders of magnitude, anodization is like 1,000x~5,000x thicker (5~25µm) than the natural oxide coating (~5nm).
