Aircraft structures, rivets, missile components, truck hubs, propeller components and other structural components.
According to the different metal elements contained in the aluminum rod, the aluminum rod can be divided into 8 categories, that is, it can be divided into 9 series.
First, 1000 series aluminum rods represent 1050, 1060, 1100 series. The 1000 series is the most aluminum-containing series in all series. The purity can reach above 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in the conventional industry. Most of the current circulation on the market is the 1050 and 1060 series. The 1000 series aluminum plates are based on the last two Arabic numerals to determine the minimum aluminum content of the series. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand nomenclature, the aluminum content must reach 99.5% to be qualified products. China's aluminum alloy technical standards (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. The same reason, the aluminum content of the 1060 series aluminum plate must reach 99.6% or more.
Second, the 2000 series aluminum rods represent 2A16 (LY16) and 2A02 (LY6). The 2000 series aluminum plate is characterized by high hardness, and the copper content is the highest, about 3-5%. The 2000 series of aluminum rods are aerospace aluminum and are currently not commonly used in conventional industries.
2024 is a typical hard aluminum alloy in the aluminum-copper-magnesium system. It is a heat treatable alloy with high strength, easy processing, easy turning and corrosion resistance.
After heat treatment (T3, T4, T351), the mechanical properties of 2024 aluminum rods were significantly improved. The T3 state parameters were as follows: tensile strength 470 MPa, 0.2% yield strength 325 MPa, elongation: 10%, fatigue strength 105 MPa, hardness 120HB.
Main uses of 2024 aluminum rods: aircraft structures, rivets, truck hubs, propeller assemblies and other structural components
Third, the 3000 series aluminum rods represent 3003 and 3A21. China's 3000 series aluminum sheet production process is relatively good. The 3000 series aluminum rods are mainly composed of manganese. The content is between 1.0 and 1.5, which is a series with better anti-rust function.
Fourth, the 4000 series aluminum rods represent the aluminum sheets of the 4A01 4000 series, which belong to the series with higher silicon content. Typically the silicon content is between 4.5 and 6.0%. It is a building material, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance, product description: heat-resistant, wear-resistant
Five, 5000 series aluminum rods represent 5052, 5005, 5083, 5A05 series. 5000 series aluminum rods belong to the more common alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. It is also widely used in conventional industries. In China, 5000 series aluminum plates belong to one of the more mature aluminum plate series.
Sixth, 6000 series aluminum rods represent 6061 mainly contain two elements of magnesium and silicon, so the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product, which is suitable for applications with high corrosive and oxidizing requirements. Good workability, easy coating and good processability.
Seven, 7000 series aluminum rods represent 7075 mainly containing zinc. Also belonging to the aviation series, it is an aluminum-magnesium-zinc-copper alloy, which is a heat-treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. At present, it basically relies on imports, and China's production process needs to be improved.
Eight, 8000 series aluminum rods are commonly used 8011 belong to other series, most of the applications are aluminum foil, the production of aluminum rods is not very common.
