Aluminium bar is a kind of aluminium products, the melting and casting of aluminium bar includes melting, purification, impurity removal, gas removal, slag removal and casting process.
According to the different metal elements contained in the aluminium bar, aluminium bar can be divided into 8 categories, that is, can be divided into 9 series:
1、1000 series aluminium rods represent 1050, 1060, 1100 series. In all series 1000 series belongs to a series with the most aluminium content. The purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively single, the price is relatively cheap, and it is one of the most commonly used series in the conventional industry at present. Most of the market circulation for the 1050 and 1060 series.
2、2000 series aluminium rods on behalf of the 2A16 (LY16), 2A02 (LY6). 2000 series aluminium rods are characterized by high hardness, which is the highest content of copper elements, probably in the 3-5%. 2000 series aluminium rods belong to the aerospace aluminium, in the conventional industry is not often used.
3、3000 series aluminium rods on behalf of 3003, 3A21-based. China's 3000 series aluminium bar production process is more excellent. 3000 series aluminium 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 aluminium rods Represented by 4A01 4000 series aluminium rods belong to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%. It is a building material, mechanical parts, forging material, welding material; low melting point, good corrosion resistance, Product Description: heat-resistant, wear-resistant properties.
5、5000 series aluminium bar Representing 5052, 5005, 5083, 5A05 series. 5000 series aluminium bar belongs to the more commonly used alloy aluminium bar series, the main element is magnesium, magnesium content between 3-5%. It can also be called aluminium-magnesium alloy. The main features are low density, high tensile strength and high elongation. In the same area under the weight of aluminium-magnesium alloy is lower than other series, in the conventional industry is also more widely used. In our country 5000 series aluminium bar belongs to one of the more mature aluminium bar series.
6、 6000 series aluminium rods on behalf of 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 aluminium forging products, suitable for anti-corrosive, oxidation requirements of high application. Good usability, easy coating, good processability.
7、7000 series aluminium bar On behalf of 7075 Mainly contains zinc. Also belongs to the aviation series, is aluminium-magnesium-zinc-copper alloy, is a heat-treatable alloy, belongs to the super-hard aluminium alloy, has good wear resistance.
8、8000 series aluminium rods more commonly used for the 8011 belongs to other series, most of the applications for aluminium foil, the production of aluminium rods are not very commonly used.
