Aluminum materials are generally divided into several series and their respective contents

The specific meaning and difference of aluminum material numbering:
1 series (representing pure aluminum, with an aluminum content of not less than 99%)
2 series (mainly made of copper alloy)
3 series (mainly manganese)
4 series (mainly composed of silicon)
5 series (mainly magnesium)
6 series (mainly composed of magnesium and silicon)
7 series (mainly zinc)
8 Series (Other Elements)
1、 The 1000 series represents 1050 1060 1070. The 1000 series aluminum plate, also known as pure aluminum plate, belongs to the series with the highest aluminum content among all series. The purity can reach over 99.00%. Due to the absence of other technical elements, the production process is relatively simple and the price is relatively cheap, making it a commonly used series in conventional industry.

Currently, the majority of products in circulation on the market are the 1050 and 1060 series. The minimum aluminum content of the 1000 series aluminum plate is determined based on the last two Arabic numerals. For example, for the 1050 series, the last two Arabic numerals are 50. According to the naming principle of the brand, the aluminum content must reach above 99.5% to be a qualified product. The technical standard for aluminum alloys in China (gB/T3880-2006) also specifies that the aluminum content in 1050 should reach 99.5% The same principle applies to 1060 series aluminum plates, which must have an aluminum content of at least 99.6%.

2、 The 2000 series aluminum plate represents 2A16 (LY16) 2A06 (LY6). The characteristic of the 2000 series aluminum plate is its high hardness, with a high copper content of approximately 3-5%. The 2000 series aluminum plate belongs to Hangkong aluminum material and is currently not commonly used in conventional industries.

Currently, there are few manufacturers in China producing 2000 series aluminum plates,The quality cannot be compared with foreign countries yet. At present, the imported aluminum plates are mainly provided by production enterprises in South Korea and Germany.With the development of China's aerospace industry, the production technology of 2000 series aluminum plates will be further improved.

3、 The 3000 series aluminum plate represents mainly 3003 3003 3A21. Also known as rust proof aluminum plate, the production process of China's 3000 series aluminum plate is relatively advanced. The 3000 series aluminum plate is mainly composed of manganese element.

The content is between 1.0-1.5. It is a series with good rust prevention function. Commonly used in humid environments such as air conditioners, refrigerators, and car bottoms, with a price higher than the 1000 series, it is a commonly used alloy series.
The representative of the 4000 series aluminum plate is 4A01. The 4000 series aluminum plate belongs to the series with high silicon content. The silicon content is usually between 4.5-6.0%. Belonging to building 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.
5、 The 5000 series represents the 5052.5005.5083.5A05 series. The 5000 series aluminum plate belongs to the commonly used alloy aluminum plate series, with magnesium as the main element and a magnesium content between 3-5%. Also known as aluminum magnesium alloy. The main characteristics are low density, high tensile strength, and high elongation. The weight of aluminum magnesium alloy is lower than other series under the same area Therefore, it is commonly used in hangkong, 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 and can be used for deep oxidation processing. The 5000 series aluminum plate is one of the more mature aluminum plate series in China.
6、 The 6000 series represents 6061, which mainly contains magnesium and silicon elements, thus combining the advantages of the 4000 series and 5000 series. 6061 is a cold treated aluminum forging product suitable for applications with high requirements for corrosion resistance and oxidation resistance. Good usability, excellent interface characteristics, easy coating, and good processability. Can be used on low voltage wuqi and aircraft joints.
The general characteristics of 6061 include excellent interface features, easy coating, high strength, good usability, and strong corrosion resistance.
Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, ship accessories and hardware, electronic accessories and fittings, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, valves and valve parts.
7、 The 7000 series represents 7075, which mainly contains zinc element. Also belonging to the Hangkong series, it is an aluminum magnesium zinc copper alloy, a heat treatable alloy, and an ultra hard aluminum alloy with good wear resistance. The 7075 aluminum plate is stress relieved and will not deform or warp after processing All oversized and ultra thick 7075 aluminum plates have undergone ultrasonic testing to ensure no sand holes or impurities. 7075 aluminum plates have high thermal conductivity, which can shorten molding time and improve work efficiency.

The main feature is that 7075 is a high hardness and high strength aluminum alloy, commonly used in the manufacturing of aircraft structures and futures. It requires high stress structural components and mold manufacturing with high strength and strong corrosion resistance. At present, we mainly rely on imports, and our country's production technology still needs to be improved.
