Aluminum 1100 Properties & Products

Cold-working is the most common way to form aluminum 1100. A cold metalworking process is any metal shaping or forming process that takes place at or near room temperature. Aluminum 1100 can be shaped into many different products, including chemical equipment, railroad tank cars, fin stock, dials, name plates, cooking utensils, rivets, reflectors and sheet metal. The plumbing and lighting industries also use aluminum 1100, as do a wide variety of other industries.

Aluminum 1100 is among the softest aluminum alloys and therefore is not used for high-strength or high-pressure applications. Though it is often cold-worked, pure aluminum can be hot-worked as well, but more frequently, aluminum is shaped by spinning, stamping and drawing processes, none of which require the use of high heat. These processes produce aluminum shapes in the form of foil, plates, round bars or rods, sheets, strips, and wire. Aluminum 1100 can also be welded; resistance welding is possible, but it can be difficult and usually requires the attention of skilled welders. Aluminum 1100 is just one of several common aluminum alloys and is soft, low strength and, at 99% min aluminum, is the commercially pure aluminum. Copper, iron, magnesium, manganese, silicon, titanium, vanadium and zinc comprise the remaining elements. It cannot be hardened by heat treatment and is very formable.
