According to the aluminum bar contains different metal elements, aluminum bars may be divided into 8 major categories, that is, can be divided into 9 series:
The first and 1000 series of aluminum bars represent the 1050, 1060 and 1100 series. In all series, the 1000 series belongs to a series with the largest amount of aluminum. Purity can reach more than 99%. 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 industries. Most of the circulation on the market is for the 1050 and 1060 series. 1000 series aluminium rods to determine the minimum aluminum content in this series according to the amount of the last two Arabia figures, such as the 1050 series of the last two Arabia number 50, according to the international brand naming principles, content must reach 99.5% to the top for qualified products. China's aluminum alloy technology standard (gB/T3880-2006) is also clearly defined, 1050 aluminum content of 99.5%., the same reason, 1060 series aluminum bar aluminum content must reach more than 99.6%.
The two and 2000 series aluminum rods represent 2A16 (LY16) and 2A02 (LY6). 2000 series aluminum bars are characterized by higher hardness, in which the highest content of copper, probably around 3-5%. The 2000 series aluminum bars belong to aviation aluminum and are not used in the conventional industry.
2024 typical aluminum alloy aluminum copper magnesium is the case of heat treated alloy, high strength, easy processing, easy cutting, general corrosion resistance.
2024 aluminum bar after heat treatment (T3, T4, T351), the mechanical properties improved significantly, as the T3 state parameters: tensile strength of 470MPa, 0.2% yield strength 325MPa, elongation 10%, fatigue strength of 105MPa, hardness of 120HB.
2024. Main uses of aluminum bars: aircraft structures, rivets, truck hubs, propeller assemblies, and many other structures
The three and 3000 series aluminum bars represent 3003 and 3A21. The production process of 3000 series aluminum bars in China is excellent. The 3000 series aluminum rods are made up of manganese. The content is between 1.0-1.5, it is a series of antirust function better.
The four and 4000 series aluminum bars represent the 4A01 4000 series aluminum bars, which belong to a series of high silicon content. Usually the silicon content is between 4.5-6.0%. Construction materials, mechanical parts, forging materials, welding materials, low melting point, good corrosion resistance, product description: a heat-resistant, wear-resistant characteristics
The five and 5000 series aluminum bars represent the 5052, 5005, 5083, and 5A05 series. The 5000 series aluminum bars belong to the commonly used alloy aluminum bar series, the main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum magnesium alloy. The main characteristics are low density, high tensile strength and high elongation. In the same area, the weight of Al Mg alloy is lower than other series, and it is widely used in the conventional industry. In our country, the 5000 series aluminum bar is one of the mature aluminum bars.
Six, 6000, 6063 representatives of the 6061 series aluminum rod mainly contains two elements of magnesium and silicon, so the advantages of 4000 series and 5000 Series 6061 is a cold forging processing of aluminum products, suitable for applications in corrosion resistance, oxidation resistance of high requirements. The utility model has the advantages of good usability, easy coating and good processability.
The seven and 7000 series of aluminum bars represent 7075, mainly containing zinc. Also belong to Aviation series, is aluminum, magnesium, zinc, copper alloy, is a heat treatable alloy, belongs to ultra hard aluminum alloy, has good wear resistance. Basically rely on imports, China's production process has yet to be improved.
The eight and 8000 Series aluminum bars are 8011 commonly used. They belong to other series, and most of them are aluminum foil, which is not very common in the production of aluminum rods.
1, according to the content of alloy elements in different aluminum sheet can be divided into: 1 * * * for industrial pure aluminum (Al), 2 * * * for Al Cu alloy aluminum (Al--Cu), 3 * * * aluminum manganese alloy aluminum (Al--Mn), 4 * * * for aluminum (aluminum silicon alloy Al--Si), 5 * * * for aluminum magnesium alloy aluminum (Al--Mg), 6 * * * for Al Mg Si alloy aluminum (AL--Mg--Si), 7 * * * for aluminum and zinc alloy aluminum [AL--Zn--Mg-- (Cu)], 8 * * * for aluminum and other elements. Each series but also with three bits, each bit must be numbers or letters, the meaning is: second digit number controlled impurities; third, fourth digits representing the lowest content of pure aluminum content percentage after the decimal point.
2, according to the shape can be divided into: round aluminum bar, square aluminum rod, six angle aluminum rod, trapezoidal aluminum rod.
