Aluminum is a silver-colored, low density metal. It is used in a wide 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 with the addition of appropriate alloying elements (Cu, Mg, Mn, Si, etc.) and subsequent heat/work treatments. It is commonly used in both wrought and cast forms. The metal's low density 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 in architectural uses.

|Cast Aluminum||Cast aluminum is a specific metal that has gone through a process known as casting. It is created when methods such as die casting, mold casting, or sand casting are used to temper the aluminum for use in creating components for many different types of products. This form of aluminum is used for a number of items around the house, as well as machinery and other products that are necessary to the manufacturing of a wide range of goods and services.|
