1100 aluminum sheet is commonly available in two tempers - O temper (annealed state) and H14 temper (cold worked state), with different characteristics and applications. 1100 o aluminum sheet is a pure aluminum plate, where “O” indicates that the material is in a fully annealed state, i.e. heat-treated without cold working, and therefore has very good plasticity and low strength. 1100 H14 means that the aluminum alloy has been partially hardened by cold working, which gives it high strength and hardness while maintaining a certain degree of ductility. 1100 H14 aluminum sheet is suitable for applications requiring a certain degree of strength and rigidity such as structural parts, mechanical components, etc.
Here are some features and applications about 1100 O aluminum sheet:
Features:
- High purity: the aluminum content of 1100 series aluminum sheet is usually not less than 99% with high purity.
- Good corrosion resistance: Due to its high purity, 1100 aluminum sheet has good corrosion resistance under atmospheric conditions, especially suitable for applications in contact with chemicals or in marine environments.
- Excellent formability: the 1100 O aluminum sheet in the fully annealed state is very soft, easy to bend, stamping, deep drawing and other processing, suitable for making complex shaped parts.
- Good weldability: it can be joined by a variety of welding methods, including resistance welding and gas shielded welding.
- Good electrical and thermal conductivity: due to its high aluminum content, 1100 O aluminum sheet has good electrical and thermal conductivity.
Applications:
- Chemical equipment: such as storage tanks, reactors, pipelines, etc., utilizing its corrosion resistance.
- Decorative materials: such as architectural curtain walls, interior decorative panels, etc., taking advantage of its good surface treatment properties and aesthetics.
- Transportation tools: such as cars, trains, airplanes, internal components, using its lightweight properties.
- Electrical products: such as heat sinks, cables, etc., to take advantage of its good electrical and thermal conductivity.
- Food packaging: such as can boxes, aluminum foil, etc., using its non-toxic, hygienic, easy to form.
In summary, the 1100 o aluminum sheet is suitable for applications requiring high plasticity and formability, while 1100 H14 aluminum sheet is suitable for applications where strength and rigidity are required. Choosing the right state can be determined by the specific application requirements.
