Aluminum plate is made of pure aluminum or aluminum alloy material through the pressure processing (shear or sawing) to obtain a rectangular cross-section rectangular thickness uniform material. Internationally, aluminum material having an thickness of 0.2 mm or more and 500 mm or less and a length of 16 mm or less is referred to as an aluminum sheet or an aluminum sheet. 0.2mm The following is the aluminum foil, within the width of the strip material or bar.
The main use of aluminum is:
1, lighting 2, solar reflector 3, architectural appearance 4, interior decoration: ceilings, walls, etc. 5, furniture, cabinets 6, elevators 7, signs, nameplate, luggage 8, car interior and exterior decoration 9., interior decorations: Such as frame 10, household appliances: refrigerators, microwave ovens, audio equipment, etc. 11, aerospace and military aspects, such as China’s current large aircraft manufacturing, Shenzhou spacecraft series, satellite and so on.
Classification of aluminum grades
According to the aluminum plate contains different metal elements, aluminum can be divided into nine categories, that is, can be divided into nine series, the following gradually about
First, 1000 series on behalf of 1050 1060 1070 1000 series aluminum plate is also known as pure aluminum, in all series 1000 series is the largest amount of aluminum in a series. Purity can reach more than 99.00%. Because it does not contain other technical elements, so the production process is relatively simple, the price is relatively cheap, is the most commonly used in conventional industry a series. Most of the current market circulation for the 1050 and 1060 series. 1000 series aluminum plate according to the last two Arabic numerals to determine the minimum aluminum content of this series, such as 1050 series of the last two Arabic numerals for 50, according to the international grade naming principle, aluminum content must reach 99.5% or more for qualified products. China’s aluminum alloy technical standards (GB / T3880-2006) also clearly stipulates that 1050 aluminum content of 99.5%. The same reason 1060 series aluminum plate aluminum content must reach more than 99.6%.
Second, 2000 series aluminum plate on behalf of 2A16 (LY16) 2A12 (LY12) 2A06 (LY6) 2000 series of aluminum is characterized by a higher hardness, of which the highest content of copper, about 3-5%. 2000 series of aluminum is an aviation aluminum, which is not commonly used in conventional industries. China’s current production of 2000 series of aluminum manufacturers less. Quality can not be compared with foreign countries. The current imports of aluminum is mainly provided by South Korea and Germany production enterprises. With the development of China’s aerospace industry, 2000 series of aluminum production technology will be further improved.
Three, 3000 series aluminum plate on behalf of 3003 3003 3A21 mainly. But also can be called anti-rust aluminum plate 3000 series of aluminum production process is more excellent. 3000 series aluminum is composed of manganese as the main component. Content between 1.0-1.5. Is a better series of anti-rust function. Conventional applications in air conditioning, refrigerators, car and other humid environment, the price is higher than the 1000 series, is a more commonly used alloy series.
Four, 4000 series aluminum plate for the 4A01 4000 series of aluminum is a high series of silicon content. Usually silicon content between 4.5-6.0%. Is a building materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance Product Description: with heat, wear characteristics
Five, 5000 series on behalf of 5052.5005.5083.5A05 series. 5000 series of aluminum is a more commonly used series of aluminum alloy, the main element of magnesium, magnesium content between 3-5%. It can be called aluminum-magnesium alloy. The main features of low density, high tensile strength, high elongation. In the same area under the weight of aluminum-magnesium alloy is lower than the other series. Therefore, commonly used in aviation, such as aircraft fuel tank. In the conventional industry is also more widely used. Processing technology for continuous casting and rolling, are hot-rolled aluminum series can do deep processing of oxidation. In our 5000 series aluminum plate is one of the more mature aluminum series.
Six, 6000 series represents 6061 mainly contains two elements of magnesium and silicon, so the focus of the 4000 series and 5000 series of advantages 6061 is a cold treatment of aluminum forging products, suitable for corrosion resistance, high oxidation requirements of the application. Can be useful, excellent interface characteristics, easy coating, good processing. Can be used for low-voltage weapons and aircraft joints.
6061 general characteristics: excellent interface features, easy coating, high strength, good usability, strong corrosion resistance.
6061 Typical use of aluminum: aircraft parts, camera parts, couplings, marine accessories and hardware, electronic accessories and fittings, decorative or all kinds of hardware, hinge head, head, brake piston, hydraulic piston, electrical accessories, valves and valve parts The
Seven, 7000 series representative 7075 mainly contains zinc. Also belong to the aviation series, is aluminum magnesium zinc copper alloy, is heat treatment alloy, are super-hard aluminum alloy, a good wear resistance .7075 aluminum plate is the elimination of stress, after processing will not deformation, warping. Thick 7075 aluminum plate all by ultrasonic detection, can guarantee no trachoma, impurities .7075 aluminum plate thermal conductivity is high, can shorten the molding time, improve work efficiency. The main feature is the hardness of 7075 is high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structure and futures. It requires high strength, high corrosion resistance of high-stress structural parts, mold manufacturing. At present, basically rely on imports, China’s production process has yet to be improved.
