Aluminum 1100 is one of the most widely used alloys, with excellent forming properties, especially in the fully soft, annealed temper. It may be suitable for applications that require bending, spinning, drawing, stamping and roll forming. It has good thermal conductivity and is often used in heat exchangers and as heat sinks in electrical applications.

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.

The following is a detailed introduction to 1100 aluminum plates/sheets:

Common 1100 Aluminum Sheet Metal Tempers

Aluminum tempers consist of numbers and letters, which indicate the type of treatment the alloy has undergone to achieve the desired mechanical properties. Several of the most common tempers for 1100 aluminum sheet include:

O

H14

H18

O indicates annealed aluminum and is the softest grade of the alloy. H18 is among the hardest tempers with the highest tensile strength. Champagne Metals stocks various thicknesses and sizes of 1100 sheet aluminum to cover your needs.

Aluminum 1100 Sheet Chemical Properties

The chemical composition of 1100 sheet aluminum is 99% to 99.9% pure aluminum. Minor residuals include copper, iron, manganese and silicon.

Mechanical Properties of Aluminum Sheet 1100

Several primary mechanical properties of aluminum sheet 1100 include tensile strength, yield strength and hardness. Typical tensile strength ranges from 75 megapascals (MPa) to 110 MPa, while yield strength varies from 30 MPa to 55 MPa. Hardness is typically 23 HB to 28 HB on the Brinell scale.
