The Uses of 1100 Aluminum

What is 1100 Aluminum?

Aluminum 1100 is also called Commercial Grade Aluminum and is an almost pure Aluminum alloy. Generally, 1100 is over 99% aluminum with less than one percent of copper, iron, manganese, silicon, titanium, vanadium, and zinc mixed in for a little extra strength.

It is known for its superior corrosion resistance, formability, conductivity, and high weldability. However, 1100 is quite soft and therefore not used in applications that require high strength or hardness. Instead, it is typically used for chemical equipment, food handling equipment, utensils, rivets, decorative trim, decorative parts, dials and name plates, lighting equipment, heat exchangers, and sheet metal work.

1100 Aluminum is also very sensitive to heat variance. At temperatures ranging from 392 – 482 °F (200 – 250 °C) 1100’s already lower strength decreases even further. However, at sub-zero temperatures, its strength actually increases. This makes 1100 an ideal low-temperature alloy.

How do you work 1100?

Cold-working is the optimal way of dealing with the alloy. High heat should be avoided. For these reasons, fabricators typically stamp, roll, draw, and spin 1100 as those keep temperatures down. While it is easy to hot work 1100, the further reduction in strength means it is generally avoided.

The alloy can be hardened by cold working, but not by hot working nor heat treatment.

1100 is suitable for welding using AL 1100 consumable electrodes and filler wire.
