1000 series
1000 series aluminum coil is also known as pure aluminum coil. Among all series, 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 metals and technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series of conventional industrial aluminum. Most of the circulation on the market is 1050, 1060 and 1100 series. The 1000 series aluminum coil 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 more than 99.5% to be qualified products. my country's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 should reach 99.5%; for the same reason, the aluminum content of 1060 series aluminum coil must reach more than 99.6%.
2000 series
There are mainly 2A16 (LY16), 2A06 (LY6), 2000 series. This type of aluminum coil is characterized by high hardness, among which the copper content is the highest, about 3-5%. 2000 series aluminum sheets belong to aviation aluminum materials, which are not often used in conventional industries. At present, the manufacturers of 2000 series aluminum sheets are mainly manufacturers in China, Japan and Germany. With the development of my country's aerospace industry, the production technology of 2000 series aluminum sheets will be further improved.
3000 series
There are mainly 3003 3003 3A21 series, which can also be called anti-rust aluminum coils. The production process of 3000 series aluminum coils in my country is relatively excellent. 3000 series aluminum coil is mainly composed of manganese element. The content is between 1.0-1.5. It is a series with better anti-rust function. It is routinely used in humid environments such as air conditioners, refrigerators, and car bottoms. The price is higher than the 1000 series. It is a more commonly used alloy series.
4000 series
There are mainly 4A01 4000 series, which belong to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%. It belongs to building materials, forging materials, mechanical parts, welding materials; low melting point, good corrosion resistance, heat resistance and wear resistance.
5000 series
There are mainly 5052.5005.5083.5A05 series. 5000 series aluminum coil belongs to the more commonly used alloy aluminum coil series, the main element is magnesium, and the magnesium content is between 3-5%. Also known as 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 that of other series. Therefore, it is often 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 series of hot-rolled aluminum coils, so it can be deep-processed by oxidation. In my country, the 5000 series aluminum coil belongs to one of the more mature aluminum coil series.
6000 series
There are mainly 6061 series, containing two elements of magnesium and silicon, so the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-treated aluminum forging product, which is suitable for applications with high requirements for corrosion resistance and oxidation resistance. Good usability, excellent interface characteristics, easy coating, and good workability. Can be used on low voltage weapons and aircraft joints.
Features of 6061: Excellent interface characteristics, easy coating, high strength, good usability, 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 .
7000 series
There are mainly 7075 series, which contain 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 coil is stress-relieved and will not be deformed or warped after processing. The thick 7075 aluminum coil is all ultrasonically detected, which can ensure no blisters and impurities. The high thermal conductivity of the 7075 aluminum coil can shorten the molding time and improve the work efficiency. The main feature is that the hardness is high. 7075 is an aluminum alloy with high hardness and high strength, which is often used in the manufacture of aircraft structures and futures. It requires high-strength structural parts and mold manufacturing with high strength and strong corrosion resistance.
8000 series
The more commonly used 8011 belongs to other series. The aluminum coil with the main function of the bottle cap is also used in the radiator, and most of the applications are aluminum foil.
9000 series
Belongs to the spare series. With the continuous development of science and technology, in order to cope with the emergence of aluminum sheets containing other alloying elements, the International Federation of Aluminum Sheets and Strips has specially indicated that the 9000 series is a spare series, waiting for another new variety to appear to fill the gap of the 9000 series.
