Aluminum bar is a kind of aluminum products, the melting and casting of aluminum bar includes melting, purifying, removing impurities, removing gas, removing slag and casting process.
According to the different metal elements contained in aluminum rods, aluminum rods can be roughly divided into 8 major categories, that is, can be divided into 9 series:
1, 1000 series aluminum rods mainly 1050, 1060, 1100 series. In all series in the 1000 series belongs to the aluminum content of a series. Purity can reach more than 99.00%. Because it does not contain other technical elements, so the production process is relatively single, the price is relatively cheap, is currently a series commonly used in the conventional industry.
Most of the market circulation for the 1050 and 1060 series. 1000 series of aluminum rods according to the two Arabic numerals to determine the aluminum content of this series, such as 1050 series of two Arabic numerals for the 50, according to the international brand naming principles, the aluminum content must reach 99.5% or more for qualified products.
China's aluminum alloy technical standards (gB/T3880-2006) also clearly stipulates that 1050 aluminum content of 99.5%. The same reason 1060 series aluminum bar aluminum content must reach 99.6% or more.
2, 2000 series aluminum bar mainly 2A16 (LY16), 2A02 (LY6). 2000 series aluminum bar is characterized by high hardness, which to the copper element content, probably in the 3-5%. 2000 series aluminum bar belongs to the aerospace aluminum, in the conventional industry is not often used.
2024 for aluminum - copper - magnesium system in the typical hard aluminum alloy, is a heat-treatable alloy, high strength, easy to process, easy to turn, corrosion resistance in general.
2024 aluminum bar after heat treatment (T3, T4, T351), mechanical properties improve, its T3 state parameters are as follows: tensile strength 470MPa, 0.2% yield strength 325MPa, elongation: 10%, fatigue strength 105MPa, hardness 120HB.
The main use of 2024 aluminum bar: aircraft structure, rivets, truck hubs, propeller components and other structural parts.
3, 3000 series aluminum bar 3003, 3A21 mainly. China's 3000 series aluminum bar production process is more excellent. 3000 series aluminum bar is made of manganese as the main component. The content is between 1.0-1.5, it is a series with better anti-rust function.
4, 4000 series aluminum rods are mainly 4A014000 series aluminum rods belong to the series with higher silicon content. Usually between 4.5-6.0% silicon content. Belong to the building materials, machinery parts, forging materials, welding materials; low melting point, good corrosion resistance, product description: heat-resistant, wear-resistant features
5, 5000 series aluminum bar mainly 5052, 5005, 5083, 5A05 series. 5000 series aluminum bar belongs to the more commonly used alloy aluminum bar series, the main element is magnesium, containing magnesium between 3-5%. It can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation.
In the same area under the weight of aluminum-magnesium alloy is lower than other series, in the conventional industry applications are also more major. In our country 5000 series aluminum bar belongs to one of the more mature aluminum bar series.
6, 6000 series aluminum bar mainly 6061, 6063 mainly contains magnesium and silicon two elements, so the concentration of the 4000 series and 5000 series of advantages 6061 is a cold treatment of aluminum forging products, suitable for anti-corrosive, oxidation requirements of high application. Good usability, easy coating, good processability.
7, 7000 series aluminum rods mainly 7075 aluminum rods mainly contain zinc. Also belongs to the aviation series, is aluminum-magnesium-zinc-copper alloy, is a heat treatable alloy, belongs to the super hard aluminum alloy, has good wear resistance. Basic rely on imports, our production process has to be improved.
8, 8000 series of aluminum rods more commonly used for the 8011 belongs to other series, most of the applications for aluminum foil, the production of aluminum rods are less commonly used.
