Aluminum is a metal that is used for many products, including deck and porch railings, light fixtures and outdoor furniture. Unlike steel, aluminum resists corrosion by moisture and air when exposed to the elements, but salt spray and road salts can cause a condition caused oxidation, which discolors the aluminum surface.

Acid Mine Drainage: Chemistry. The orange color is caused by ferric hydroxide ( Fe (OH) 3 ) precipitating out of the water. The precipitate forms as the acid mine drainage becomes neutralized. At low pH values, the metal ions remain soluble. When the pH rises, the iron oxidizes and precipitates out.
