Aluminum has the characteristics of light specific gravity, small springback during forming, high strength, good plasticity, and excellent conductivity, thermal conductivity, and corrosion resistance. At present, the surface treatment processes of aluminum, such as anodic oxidation, drawing, and sandblasting, have been well developed, so it has been widely used in various industries.
Currently, aluminum is mainly divided into eight series.
- 1000 Series: industrial pure aluminum
The 1000 series is more than 99% pure aluminum series, such as 1050, 1100, etc. Among all series, the 1000 series has the highest aluminum content, with a purity of more than 99.00%. The formability and surface treatment of the 1000 series are good, and it has the best corrosion resistance in aluminum alloys. However, its strength is relatively low, and it is mainly used to make decorative or interior parts. - 2000 Series:AL-CU series
The 2000 series is an aluminum-copper alloy series, with a copper content of about 3-5%, such as 2014. It is characterized by high hardness, but poor corrosion resistance. The 2000 series aluminum rod is aviation aluminum, used as a construction material, and is not commonly used in conventional industries. - 3000 Series:AL-Mn series
The 3000 series is an aluminum-manganese alloy series, such as 3003. The 3000 series aluminum rod takes manganese as the main additive, with a content of 1.0-1.5. It is a series with good rust prevention functions, often used in the production of liquid product tanks, cans, construction processing pieces, construction tools, various lamp parts, and thin sheet processing of various pressure vessels and pipelines. Its formability, weldability, and corrosion resistance are all good. - 4000 Series:AL-Si series
The 4000 series is an aluminum-silicon alloy series, such as 4032. Usually, the silicon content is between 4.5-6.0%, and the higher the silicon content, the higher the strength. The 4000 series aluminum alloy has a low melting point, good corrosion resistance, and heat resistance, and wear resistance. It is often used as a building, mechanical parts, forging, welding, and other materials. - 5000 Series:AL-Mg series
The 5000 series is an aluminum-magnesium alloy series, such as 5052. The 5000 series aluminum rod is a commonly used alloy aluminum plate series, and the main element, magnesium, has a content of 3-5%, also known as aluminum-magnesium alloy. Its main features are low density, high tensile strength, and high elongation. Under the same area, the weight of the aluminum-magnesium alloy is lower than that of other series, and it is widely used in conventional industries. The most commonly used 5052 is a representative alloy with medium-strength, and its corrosion resistance, weldability, and formability are good. It is especially fatigue-resistant and has good sea water corrosion resistance, and is often used to make products with high strength requirements. - 6000 Series:AL-Mg-Si series
The 6000 series is an aluminum-magnesium-silicon alloy series, such as 6061, 6063, etc. The 6000 series aluminum alloy represents 6061, which mainly contains two elements, magnesium and silicon, thus combining the advantages of the 4000 series and the 5000 series. 6061 is a cold-worked forging product, suitable for applications with high corrosion resistance and oxidation resistance requirements. The 6000 series aluminum alloys are often cast to form and can cast more complex structures. They can be used to make parts with snaps, such as battery covers. - 7000 Series:AL-Zn-Mg series
The 7000 series is an aluminum-zinc alloy series, such as 7001, etc., mainly containing zinc elements. Another representative of the 7000 series aluminum alloys, 7075, also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy and is a heat-treatable alloy. It belongs to super-hard aluminum alloys with good wear resistance. Currently, it basically relies on imports. - 8000 Series:others
The 8000 series is a alloy system other than the above. The 8000 series aluminum alloy is more commonly used as 8011, which belongs to other series. Most of its applications are aluminum foil, and it is not commonly used in the production of aluminum rods.
