How to Oxidize Aluminum | eHow

30.08.2017· Aluminum has a high strength-to-weight ratio, and its patina is the same color as the metal. Therefore, many industries use aluminum, in place of steel or plastic, for strong, lightweight parts that resist corrosion. However, the aluminum surface does oxidize, and oxidation weakens the metal.

Does Aluminum Rust? | All Metals Fabriion

Aluminum oxide appears as a powdery white or dull gray coating. As oxidation occurs, it hardens and creates a protective layer over the newly exposed areas of corroded aluminum. The aluminum corrosion process is actually halted by oxidation – the metal won’t continue to deteriorate unless the aluminum oxide is removed.

Aluminum Anodizing | Industrial Metal …

The aluminum oxide layer has much higher corrosion and abrasion resistance than aluminum. The anodizing step takes place in a tank that contains a solution of sulfuric acid and water. After anodizing is complete, the parts can be immersed in an optional coloring tank, to achieve a deep black tone instead of the standard clear or silver finish.
