Product Details

1100-O aluminum sheet is a commercially pure aluminum sheet in the fully annealed condition. With aluminum content of 99.0% or higher, it provides excellent formability, corrosion resistance, thermal conductivity, and welding performance. This makes it suitable for deep drawing, food containers, chemical equipment, reflectors, and decorative applications.

The “O” temper means the aluminum has been fully annealed to achieve the softest condition. Compared with strain-hardened 1100-H14, 1100-O aluminum sheet is selected when maximum forming ability is more important than strength.

What Is 1100-O Aluminum Sheet?

1100 aluminum belongs to the 1000 series pure aluminum family. It contains very high aluminum content with only small amounts of alloying elements, providing excellent corrosion resistance and electrical performance.

1100-O Aluminum Definition:
1100 = Commercially pure aluminum alloy
O = Fully annealed temper for maximum softness and formability

1100 Aluminum Chemical Composition

The high aluminum purity gives 1100-O excellent corrosion resistance and surface finishing performance. Unlike heat-treatable alloys, 1100 aluminum gains strength mainly through cold working rather than heat treatment.

Element	Typical Content
Aluminum (Al)	≥99.0%
Copper (Cu)	0.05-0.20%
Other Elements	Small controlled amounts

1100-O Aluminum Sheet Mechanical Properties

The O temper provides the lowest strength and highest ductility among common 1100 conditions. It is widely selected for applications requiring deep drawing and complex forming.

Property	Typical Value
Tensile Strength	Approximately 75-105 MPa
Elongation	30% or higher
Temper	O (Fully Annealed)
Density	Approximately 2.71 g/cm³

1100-O Aluminum Sheet Specifications

1100-O aluminum sheet is commonly supplied for forming applications where flexibility and surface quality are important.

Item	Typical Range
Thickness	0.3-6 mm
Temper	O
Product Form	Sheet and coil

Why Choose 1100-O Aluminum Sheet?

1100-O is preferred when manufacturers need maximum softness, easy processing, and excellent corrosion resistance.

Feature	Benefit
High Purity Aluminum	Excellent corrosion resistance
Fully Annealed Condition	Maximum deep drawing ability
Good Thermal Conductivity	Suitable for heat transfer applications
Excellent Weldability	Easy fabrication and repair

Applications of 1100-O Aluminum Sheet

The combination of softness, corrosion resistance, and clean surface appearance makes this material suitable for many industrial and commercial uses.

Application	Reason for Selection
Food Containers	Non-toxic surface and corrosion resistance
Chemical Equipment	Resistance to many chemical environments
Reflectors	High reflectivity and finishing quality
Deep Drawing Parts	Excellent elongation and forming ability

1100-O vs 1100-H14 Aluminum Sheet

Both materials use the same aluminum alloy, but their mechanical properties are different because of temper processing. The selection depends on whether forming or strength is the priority.

Comparison	1100-O	1100-H14
Condition	Fully annealed	Strain hardened
Strength	Lower	Higher
Formability	Excellent	Moderate
Main Use	Deep drawing and complex forming	Panels and general fabrication

Surface Treatment of 1100-O Aluminum Sheet

Due to its high purity, 1100 aluminum provides excellent surface finishing performance. It can be anodized, polished, or coated depending on appearance requirements.

Anodizing: improves surface protection and appearance.
Polishing: creates a bright reflective finish.
Coating: adds color and additional protection.

Deep Drawing Performance of 1100-O Aluminum

The soft temper condition makes 1100-O suitable for deep drawing tests and prototype development. Manufacturers often use sample testing before mass production of formed components.

Recommended Applications:
Deep drawing containers, formed covers, reflectors, and customized aluminum parts requiring maximum ductility.
