1100-O aluminum is the annealed state of 1100 aluminum. Compared to other variations of 1100 aluminum, it has the highest formability.

What is 1100 O aluminum?

1100 O aluminum refers to the annealed (O) state of the 1100 aluminum alloy. This state is achieved by heating the alloy to a specific temperature and then slowly cooling it to relieve internal stresses and enhance its formability.

1100-O aluminum is highly valued for its excellent formability and ease of machining, although it sacrifices some strength and hardness compared to other profiles.

1100 O Aluminum Sheet Characteristics

1. Maximum Formability

1100-O aluminum offers the highest formability among the various states of 1100 aluminum. This means it can be stretched or deformed without breaking, making it an ideal choice for applications requiring high formability.

2. Enhanced Machinability

The annealed state improves the machinability of the 1100 alloy, making processes such as machining, forming, and deep drawing easier. This makes it suitable for complex shapes and intricate designs.

3. Softness and Flexibility

In the O state, 1100 aluminum is softer compared to other states, which enhances its flexibility and ability to be shaped into various forms. However, this also means that it has lower strength compared to harder tempers.

1100-O Sheet Standards

Typical surface of 1100 o aluminum sheet

Finish Type Description Applications
Bright A highly reflective, shiny surface achieved through polishing or mechanical treatments. Often used in decorative applications, automotive parts, and architectural elements where a high-gloss appearance is desired.
Polished A smooth, glossy finish created by buffing the aluminum surface to remove imperfections and enhance shine. Commonly used in applications requiring a mirror-like finish, such as in high-end consumer products and decorative panels.
Checkered A surface pattern with raised, diamond-shaped patterns or a similar design, providing both aesthetic appeal and added traction. Used in flooring, walkways, and areas requiring slip resistance and durability.
Embossed A raised pattern or design pressed into the surface of the aluminum sheet, creating a three-dimensional effect. Suitable for decorative panels, architectural features, and product branding, where a textured design is needed for visual or tactile appeal.
