Product introduction 1. Introduction of pure aluminum plate/sheet
The commonly used codes of pure aluminum plate series are 1050, 1060 and 1100. In all aluminum series, pure aluminum series belongs to a series with more aluminum content. The purity can reach 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is a series commonly used in conventional industry at present. At present, most of the 1050 and 1060 series are in circulation on the market. Calculation method of aluminum content of pure aluminum plate the lower aluminum content of pure aluminum sheet series is determined according to the last two Arabic numerals. For example, 1050 series is 50 compared with the last two Arabic numerals. According to the naming principle of all brands, the qualified product must have the aluminum content above 99.5%. China's aluminum alloy technical standard (GB / t3880-2006) also clearly stipulates that the aluminum content of 1050 can reach 99.5%. Similarly, the aluminum content of other pure aluminum plate series is calculated according to this calculation method.
General characteristics of pure aluminum plate Excellent properties of pure aluminum: 1. Low density: the density of pure aluminum is close to 2700kg / m3, about 35% of that of iron. 2. Hardenable: the strength of pure aluminum can be doubled by cold working. Moreover, it can be alloying by adding magnesium, zinc, copper, manganese, silicon, lithium, scandium and other elements, and then further strengthened by heat treatment. Its specific strength is comparable to that of high-quality alloy steel. 3. Easy processing: aluminum is cast by any casting method. Aluminum has good plasticity and can be rolled into sheet and foil; Drawing into pipes and filaments; Extrusion into a variety of civil profiles; Most machine tools can achieve a very high speed for turning, milling, boring, planing and other mechanical processing. 4. Corrosion resistance: the surface of aluminum and its alloy is easy to form a dense and firm protective film of Al2O3. This protective film will be destroyed only under the intense action of halogen ion or alkali ion. Therefore, aluminum has good resistance to atmospheric (including industrial atmospheric and marine vapor) corrosion and water corrosion. It can resist the corrosion of most acids and agricultural production systems. It can resist the corrosion of weak alkali solution by using corrosion inhibitor; The corrosion resistance of aluminum alloy can be improved by adopting protective measures. 5. No low temperature brittleness: when the temperature of aluminum is below 0 ℃, the strength and plasticity will not decrease but increase with the decrease of temperature. 6. Good electrical and thermal conductivity: the electrical and thermal conductivity of aluminum is inferior to that of silver, copper and gold. 7. Strong reflectance: the white light reflectance of polished aluminum surface is more than 80%. The higher the purity is, the higher the reflectance is. At the same time, aluminum has good reflection properties to infrared, ultraviolet, electromagnetic wave and thermal radiation. 8. No magnetism, impact and spark. 9. Sound absorption. 10. Resistance to nuclear radiation. 11. Beautiful.
Surface quality requirements of pure aluminum sheet 1. The surface of the plate shall be clean and free from cracks and oxidation debris. 2. The surface of the plate is allowed to have defects such as indentation, scratch, roll indentation, etc., but its height should not exceed the allowable negative deviation of the plate, and ensure a small thickness. 3. It is allowed to have peeling part of cladding layer and bubbles in cladding layer. 4. The surface of plate is allowed to repair the defects within the range of thickness difference. 5. Other requirements: to be drawn up by the demander and supplier.
