Compared with heat-treatable aluminum alloys, 1100 0 aluminum sheet is not designed for high-strength structural use. Its real advantage is softness and workability. It can be easily bent, stamped, spun, deep drawn, welded and formed into different shapes without cracking, which makes it a practical choice for many industrial and decorative applications.
We supply 1100 0 aluminum sheet in different thicknesses, widths, lengths and surface finishes according to project requirements. Standard sheets and custom-cut sizes are both available.
What Is 1100 0 Aluminum Sheet?
1100 aluminum is a pure aluminum alloy from the 1xxx series. The "0" or "O" temper means the sheet has been fully annealed to achieve the softest condition. This gives the material excellent flexibility and makes it suitable for parts that require forming, bending or deep drawing.
If your application needs a sheet that is easy to process, resistant to atmospheric corrosion and suitable for welding, 1100 0 aluminum sheet is often a cost-effective option.

1100 O Aluminum Sheet Machining Properties
- Weldability: 1100-O aluminum sheet has excellent weldability and is suitable for various welding methods, including TIG (tungsten inert gas) welding and spot welding. However, due to its lower strength, it is not as suitable for structural applications that require high load-bearing capacity compared to other higher-strength aluminum alloys.
- Forming and Cutting: Due to its good ductility, 1100-O aluminum sheet is easy to machine with various processes such as stamping, rolling, cutting, bending, and curling. It is commonly used to manufacture parts with complex shapes, such as aluminum containers, packaging materials, and decorative components.
1100 O Aluminum Sheet Formability and Workability
- Cold Working: Easily bent, stamped, or rolled without heat treatment. Cold working can increase strength but reduces ductility.
- Welding: Compatible with TIG, MIG, and resistance welding methods.
- Machining: Its softness makes it easy to machine, though sharp tools may be required to avoid sticking.
