Types of aluminium sheets according to the alloy grade classification, can be divided into eight major series, these series represent different alloy composition and performance characteristics. The following is a detailed introduction of each series of aluminum sheets:

1000 series aluminium sheets (pure aluminum series)
Characteristics: purity of 99.00% or more, with good formability and surface treatment, the best corrosion resistance in aluminum alloys.
Representative grades: 1050, 1060, 1070, 1100 and so on.
Applications: Commonly used in chemical equipment, ventilation ducts and other fields, also used for simple extrusion molding parts for cell phones and other electronic products.

2000 series aluminium sheets (Aluminum-Copper Alloy Series)
Characteristics: Higher hardness, but poor corrosion resistance, higher copper element content.
Representative grades: 2014, 2024, 2A16, 2A02 and so on.
Applications: partially used in aerospace, infrequently used in conventional industry.

3000 series aluminium sheets (aluminum-manganese alloy series)
Characteristics: The main component is manganese element, with good corrosion resistance.
Representative grades: 3003, 3004, 3104, 3105, 3A21 and so on.
Applications: Commonly used in environments with high weather resistance requirements, such as outdoor building decoration.

4000 series aluminium sheets (Aluminum-Silicon Alloy Series)
Characteristics: Silicon is the main alloying element, with specific physical and chemical properties.
Representative grades: 4032, 4A01, etc.
Applications: In some specific areas have applications, but not as extensive as other series.

5000 series aluminium sheets (Aluminum-Magnesium Alloy Series)
Characteristics: The main element is magnesium, containing magnesium between 3-5%, with excellent strength and corrosion resistance.
Representative grades: 5052, 5005, 5083, 5086, 5454, 5754, 5A05 and so on.
Application: Widely used in shipbuilding, automobile manufacturing and other fields, also commonly used in cell phones and other electronic products with high strength requirements.

6000 series aluminium sheets (aluminum-magnesium-silicon alloy series)
Characteristics: Containing magnesium and silicon elements, it concentrates the advantages of 4XXX series and 5XXX series, and has good mechanical properties and processing performance.
Representative grades: 6061, 6063, 6082, etc.
Applications: Widely used in aerospace, automotive manufacturing, doors and windows industry, and other fields, also commonly used in cell phones and other electronic products in the complex structure of the components.

7000 series aluminium sheets (Aluminum-Zinc Alloy Series)
Characteristics: mainly containing zinc elements, belonging to the super-hard aluminum alloy, with good wear resistance and strength.
Representative grade: 7005,7075, etc.
Applications: Mainly used in the aerospace field to manufacture high-strength, high wear-resistant parts.

8000 series aluminium sheets (other alloy series)
Characteristics: Not belonging to the above seven series of other alloy systems, composition and performance varies.
Representative grades: 8011, etc.
Application: mainly used in aluminum foil production and other fields, aluminum bar production is less commonly used.

In summary, types of aluminium sheets can be divided into eight series according to the classification of alloy grades, different alloy grades and compositions will affect the performance and use of aluminum sheet. When choosing aluminum sheets, you need to choose the right type according to the specific requirements of use and environmental conditions.
