Three, aluminum specifications 9 series
Based on the aluminum plate contains different metal elements, aluminum plate can be divided into 9 categories, that is, can be divided into 9 series, the following step by step roughly introduced.
1, 1000 series represents 1050106010701000 series aluminum plate is also known as pure aluminum plate, in all series of 1000 series belongs to the most aluminum content of a series. Purity can reach more than 99.00%.
2, 2000 series aluminum plate on behalf of the 2A16 (LY16) 2A12 (LY12) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, which is the highest content of copper elements, probably in the 3-5% or so. 2000 series of aluminum belongs to the aerospace aluminum, in the conventional industry is not often used.
3, 3000 series aluminum plate represents 300330033A21 mainly. Can also be called rust-proof aluminum plate China's 3000 series aluminum plate production process is more excellent. 3000 series aluminum plate is made of manganese as the main component. The content is between 1.0-1.5.
4, 4000 series aluminum plate represents 4A014000 series of aluminum plate belongs to the series with high silicon content. Usually between 4.5-6.0% silicon content. Belong to the building materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance. Product description: heat-resistant, wear-resistant properties.
5, 5000 series on behalf of the 5052.5005.5083.5A05 series. In our country 5000 series aluminum plate belongs to one of the more mature aluminum plate series.
6, 6000 series on behalf of the 6061 mainly contains magnesium and silicon two elements, so the concentration of the 4000 series and 5000 series of advantages of 6061 is a cold treatment of aluminum forging products.
6061 general characteristics: excellent interface characteristics, easy to coat, high strength, good availability, corrosion resistance.
Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, marine fittings and hardware, electronic fittings and connectors, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical fittings, valves and valve parts.
7, 7000 series represents 7075 mainly contains zinc. Also belongs to the aviation series, is aluminum-magnesium-zinc-copper alloy, is a heat-treatable alloy, commonly used in the manufacture of aircraft structures and futures. It requires high strength, corrosion resistance of high stress structural parts, mold manufacturing. Basic rely on imports, China's production process has to be improved. (My company once had a foreign company put forward domestic 7075 aluminum plate annealing is not uniform, appearing on the surface of the aluminum plate and internal hardness inconsistent problems)
8, 8000 series more commonly used for the 8011 belongs to other series. My memory is to do bottle caps as the main function of the aluminum plate, also used in radiators, most applications for aluminum foil. Less commonly used.
9, 9000 series belongs to the spare series, technology is so developed, in order to cope with in order to contain other alloying elements of the appearance of aluminum, the International Aluminum Sheet and Strip Federation, the special indication of the 9000 series for the spare series, waiting for a new variety to fill the gap in the 9000 series.
Four, the characteristics of the aluminum series
1 series: containing aluminum 99.00% or more, good electrical conductivity, good corrosion resistance, good welding performance, low strength, can not be strengthened by heat treatment. Application scope: high purity aluminum (containing more than 99.9% aluminum) is mainly used for scientific experiments, chemical industry and special purposes.
2 series: copper as the main element of aluminum alloy. Will also add manganese, magnesium, lead and bismuth in order to cut. Such as: 2011 alloy, in the melting process should pay attention to safety protection (will produce harmful gases). 2014 alloy with sky aviation industry, high strength. 2017 alloy than 2014 alloy strength is a little lower, but easier to process. 2014 can be heat-treated to strengthen. Disadvantages: serious tendency of intergranular corrosion. Applications: aviation industry (2014 alloy), screws (2011 alloy) and the use of higher temperature industry (2017 alloy).
3 series: manganese as the main alloying element of the aluminum alloy, not heat treatment strengthening, good corrosion resistance, good welding performance. Good plasticity. (close to super aluminum alloy). Disadvantages: low strength, but can be strengthened by cold work hardening. Easy to produce coarse grains when annealed. Applications: Seamless tubing for fuel guides used in airplanes (3003 alloy), cans (3004 alloy).
4 Series: Silicon based, not commonly used. Part of the 4 series can be heat-treated to strengthen, but there are some 4 series alloys can not be heat-treated. hr
5 series: magnesium-based. Good resistance, good welding performance, good fatigue strength, can not be heat-treated to strengthen, only cold working to improve strength. Applications: lawn mower handles, aircraft fuel tank conduit, bulletproof vests.
6 series: magnesium and silicon-based. Mg2Si for the main phase of strengthening, the most widely used alloys. 6063, 6061 with the most, the other 6082, 6160, 6125, 6262, 6060, 6005, 6463. 6063, 6060, 6463 in 6 series of lower strength. 6262, 6005, 6082. 6061 in 6 series of strength, 6061 in the 6 series of strength is relatively high. Characteristics: medium strength, good corrosion resistance, good welding performance, good process performance (easy to squeeze out of the molding) good oxidation coloring performance. Applications: cross energy tools (such as: automotive luggage racks, doors, windows, body, heat sinks, between the box shell)
7 series: zinc-based, but sometimes a small amount of magnesium, copper. One of the super hard aluminum alloy is containing zinc, lead, magnesium and copper alloy close to the hardness of steel. Extrusion speed is slower than 6 series alloys, welding performance is good. 7005 and 7075 is the highest grade in the 7 series, can be heat treatment to strengthen. Applications: aviation (bearing components of aircraft, landing gear), rockets, propellers, airships.
Eight series: aluminum alloy is 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.
Nine series: aluminum alloy is a spare alloy.
Fifth, the price of aluminum extrusion
How much does aluminum extrusion cost per ton?
General material then 18,000-19,000 yuan, the surface anodic oxidation treatment is about 22,000 yuan / ton, if the surface treatment is better, spraying, electrophoresis is more expensive.
According to the current price of aluminum ingots to calculate the words, oxidation silver white is about 18,500, electrophoresis white is about 21,000, polished oxidation 23,500 or so.
