1100 aluminum alloy is an industrially pure aluminum containing up to 99.0% aluminum and is known for its good ductility, formability, weldability and corrosion resistance. This alloy cannot be strengthened by heat treatment, but anodizing can further improve its corrosion resistance and give it an attractive surface.

The aluminum 1100 specification is available in a wide variety of products, including aluminum sheet, coil, strip and foil. These materials are commonly used to make a variety of parts that require good formability and high corrosion resistance, but do not require high strength. In addition, 1100 aluminum alloys are processed into different specifications to meet the needs of specific applications. For 1100 aluminum sheet, typical states include O (annealed), H18, H22, H12, H24, H14, H26, H16, and other states with different degrees of hardening. Thicknesses typically range from 0.3-3.0mm, widths from 900-1400mm and lengths can be customized.

Due to its unique properties, 1100 aluminum alloy has a wide range of applications in many industries:
- Electrical and electronic field: due to its good electrical and thermal conductivity, 1100 aluminum alloy is often used in the manufacture of electronic components such as heat sinks, wires, inductive coils and capacitors.
- Chemical equipment: Due to its excellent corrosion resistance, this material is also suitable for making chemical product devices and food industry devices.
- Building decoration: 1100 aluminum alloy is commonly used in building decoration materials, such as ceiling substrate, curtain wall panel substrate, as well as door and window frames. Its good workability and corrosion resistance make it an ideal choice for indoor and outdoor decoration.
- Packaging industry: Due to its excellent formability and corrosion resistance, 1100 aluminum alloy is also used in bottle caps and printing plates.
- Transportation: There are also examples of applications in bus interiors, doors and engine panels.
- Other applications: 1100 aluminum alloy is also used in deep-drawn products, cookware, aluminum for transformers, heat sinks, and other areas ranging from daily necessities to industrial equipment.

In summary, with its unique physical and chemical properties, 1100 aluminum alloy not only occupies an important position in traditional industries, but also finds new application scenarios in emerging fields as technology develops. Whether as a basic material or a finished component, 1100 aluminum alloy shows a wide range of applicability and reliability. Whether in household appliances, construction materials or high-end electronic products, we can find its figure. Therefore, understanding the specifications of 1100 aluminum alloy and its scope of application is crucial for practitioners in related industries.
