ALUMINUM

Aluminum is a silver-colored, low density (2.7 g/cc) metal that finds use in a huge variety of commercial applications. Unalloyed aluminum is ductile, exhibits moderate strength, and is very resistant to corrosion under most circumstances. Aluminum can be dramatically strengthened by the addition of appropriate alloying elements (Cu, Mg, Mn, Si, etc.) and subsequent heat/work treatments. Aluminum is commonly used in both wrought and cast forms.

The low density of aluminum results in its extensive use in the aerospace industry, and in other transportation fields. Its resistance to corrosion leads to its use in food and chemical handling (cookware, pressure vessels, etc.) and to architectural uses.
