1100 0 aluminum sheet

1100 O aluminum sheet is an annealed state of 1100 aluminum alloy, characterized by excellent ductility and outstanding formability.

Due to its superior ductility and formability, the 1100 O aluminum sheet is highly favored in applications requiring good machinability and corrosion resistance. Although it has lower strength, its wide use in food packaging, electrical, construction, and automotive industries makes it a very important material.

What is 1100 O aluminum?

1100-O aluminum refers to the "O" (annealed) state of 1100 aluminum alloy. The "O" state indicates that the alloy has been heat-treated to a specific temperature and then slowly cooled to relieve internal stresses, giving it high plasticity and making it easier to process. Compared to other states of 1100 aluminum, this process enhances its formability but reduces its strength.

1100 O aluminum alloy composition

1100-O aluminum sheet belongs to the 1100 series of aluminum alloys, with the main component being pure aluminum, typically containing 99% or higher aluminum content. The 1100 aluminum alloy is known for its excellent corrosion resistance, electrical conductivity, and thermal conductivity.
