The aluminum sheet representing the 1000 series is also called pure aluminum sheet. Among all the series, the 1000 series belongs to the series with the most aluminum content. The purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industries. Most of the products circulating in the market are 1050 and 1060 series. The 1000 series aluminum plate determines the minimum aluminum content of this series according to the last two Arabic numerals. For example, the last two Arabic numerals of the 1050 series are 50. According to the international brand naming principle, the aluminum content must reach 99.5% or more to be a qualified product. my country's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. Similarly, the aluminum content of 1060 series aluminum plates must reach 99.6% or more.
2000 series aluminum plate
Representative 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plates are characterized by higher hardness, of which the copper element content is the highest, about 3-5%. 2000 series aluminum plates are aviation aluminum materials, which are not often used in conventional industries. There are few factories producing 2000 series aluminum plates in my country. The quality cannot be compared with foreign countries. Imported aluminum plates are mainly provided by South Korean and German production companies. With the development of my country's aerospace industry, the production technology of 2000 series aluminum plates will be further improved.
3000 series aluminum plate
Mainly on behalf of 3003 3003 3A21. It can also be called anti-rust aluminum plate. my country's 3000 series aluminum plate production technology is relatively excellent. The 3000 series aluminum plate 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. It is usually used in humid environments such as air conditioners, refrigerators, and undercars. The price is higher than the 1000 series, which is a more commonly used alloy series.
4000 series aluminum plate
The aluminum plate represented by the 4A01 4000 series belongs to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%. It belongs to construction materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance Product description: It has the characteristics of heat resistance and wear resistance
Represents the 5052.5005.5083.5A05 series. The 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. In the same area, the weight of aluminum-magnesium alloy is lower than other series. Therefore, it is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series, so it can be used for deep oxidation processing. In my country, the 5000 series aluminum sheet is one of the more mature aluminum sheet series.
Representative 6061 mainly contains magnesium and silicon, so it concentrates the advantages of 4000 series and 5000 series 6061 is a cold-treated aluminum forging product, suitable for applications with high requirements for corrosion resistance and oxidation. Good workability, excellent interface characteristics, easy coating, and good processability. It can be used on low-pressure weapons and aircraft joints.
The general characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability, and strong corrosion resistance.
Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, marine accessories and hardware, electronic accessories and joints, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, valves and valve parts .
Representative 7075 mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and a super hard aluminum alloy with good wear resistance. The 7075 aluminum plate is stress-relieved and will not be deformed or warped after processing. All super super All the thick 7075 aluminum plates are ultrasonically detected, which can ensure no blisters and impurities. The 7075 aluminum plates have high thermal conductivity, which can shorten the forming time and improve work efficiency. The main feature is that the hardness of 7075 is a high-hardness, high-strength aluminum alloy, which is often used in the manufacture of aircraft structures and futures. It requires the manufacture of high-stress structural parts and molds with high strength and strong corrosion resistance. Basically relying on imports, my country's production technology needs to be improved. (The company once proposed that the domestic 7075 aluminum sheet is not uniformly annealed, and the surface and internal hardness of the aluminum sheet are inconsistent.)
The more commonly used is 8011, which belongs to other series. In my memory, the aluminum plate whose main function is to make bottle caps is also used in radiators, most of which are aluminum foil. Not very commonly used.
It belongs to the spare series, and the technology is so advanced. In order to cope with the emergence of aluminum plates containing other alloying elements, the International Aluminum Strip Federation has specially designated the 9000 series as a spare series, waiting for another new variety to appear to fill the gap of the 9000 series.
