According to the aluminum bar contains metal elements, aluminum rods probably can be divided into eight categories, namely can in nine series:
A, 1000 series aluminium rods on behalf of the 1050, 1060, 1100 series. Of all the series, 1000 series belongs to a series of aluminum content in the most. Purity can reach more than 99.00%. Because do not contain other technical elements, so the production process is single, the price is relatively cheap, is currently the most commonly used in conventional industry a series. Most of circulate on the market for 1050 and 1060 series. 1000 series aluminium rods according to the last two digits to determine the range of low aluminium content, such as series 1050, the last two digits for 50, according to the international brand naming principles, aluminum content must be more than 99.5% of qualified products. Aluminium alloy technology in China standard (gB/T3880-2006) is clearly stipulated in 1050 reached 99.5% aluminum content. In the same way the aluminum content of 1060 series aluminium rods must be above 99.6%.
2nd, 2000 series aluminium rods 2 a16 (LY16), 2 how a02 (LY6). 2000 series aluminum rod is characterized by high hardness, among them with copper content is the highest, will be about 3-5%. 2000 series aluminium rods to aviation aluminum, not often used in the conventional industry.
2024 for magnesium aluminum - copper - is typical of hard aluminum alloy, heat treatable alloys, high strength, easy processing, easy cutting, corrosion resistance.
2024 aluminum rods after heat treatment (T3, T4, T351), mechanical performance is significantly improved, its T3 state parameters are as follows: tensile strength of 470 mpa, 0.2% yield strength 325 mpa, the elongation: 10%, the fatigue strength of 105 mpa, hardness 120 hb.
2024 aluminum rod: the main purpose of aircraft structure, rivets, truck wheels, propellers component and other components
Three, 3000 series aluminium rods on behalf of 3003, 3 a21. China 3000 series aluminum rod production process is relatively good. The 3000 series aluminum rod is composed of manganese element as the main component. Content is between 1.0 to 1.5, is a good series antirust function.
Four, 4000 series aluminium rods representative for 4 a01 4000 series aluminium rods are containing a high percentage of silicon series. Usually between 4.5 6.0% silicon content. Belong to building materials, machinery parts, forging materials, welding materials; Low melting point, good corrosion resistance, the product description: has the characteristics of heat-resisting, wear-resisting
Five, 5000 series aluminium rods on behalf of the 5052, 5005, 5083, 5 a05 series. Belong to the more commonly used 5000 series aluminium rods alloy aluminum rod series, the main elements for magnesium, magnesium content between 3-5%. And could be called aluminum magnesium alloys. Main characteristics of low density, high tensile strength, elongation rate is high. Under the same area of the weight of the aluminum magnesium alloy is lower than other series, are widely used in the conventional industry. 5000 series aluminium rods in China belong to a mature one of aluminum rod series.
Six, 6000 series aluminium stick represents 6000, 6061 mainly contains two elements magnesium and silicon, so focus on the advantages of 4000 series and 5000 series, 6061 is a kind of cold treatment of aluminium forging products, applicable to against corrosion, oxidation demanding applications. Good workability, easy to coating, good workability.
7075, 7000 series aluminium rods representatives mainly contain zinc. Also belong to aircraft series, is copper alloy, aluminum and magnesium zinc is heat treatable alloys, belongs to hard aluminum alloy, have good wear resistance. Basically rely on imports, the production process needs to be improved in our country.
Eight, the 8000 series aluminum rods is relatively commonly used for the 8011 belong to other series, most of the application of aluminum foil, aluminum rod production is not too common.
