The 1100 O aluminum alloy is known for its high purity and excellent machinability. With a purity of 99.0%, this alloy is commonly used in applications requiring high electrical and thermal conductivity. The O temper provides the alloy with low hardness, enhancing its machinability and maintaining its formability. These characteristics make 1100 O ideal for applications such as electrical equipment, heat exchangers, cooling systems, decorative materials, and various industrial uses.

The 1100 O aluminum alloy is highly suitable for anodizing. Anodizing creates a protective oxide layer on the alloy's surface, increasing its corrosion resistance and providing an aesthetically pleasing finish. This feature is particularly advantageous for outdoor applications and decorative products. In terms of weldability, the 1100 O alloy performs very well. Its high purity allows for strong and reliable welds when proper welding techniques are used.

In terms of bending and forming, the 1100 O aluminum alloy is extremely flexible and easy to shape. This makes it ideal for producing complex shapes in industries such as automotive, construction, and other industrial sectors. However, due to its low strength, it is generally not suitable for high-vibration environments. This alloy is more suited for low-load and low-vibration applications.

Regarding corrosion resistance, the 1100 O aluminum alloy is highly durable due to its high purity. It shows excellent resistance to seawater, moisture, and atmospheric conditions. This makes the 1100 O alloy ideal for use in maritime applications and equipment exposed to moisture. The advantages of the 1100 O alloy include excellent machinability, good corrosion resistance, and lightweight properties, while its disadvantages include low strength and limited performance under high temperatures.
