The aluminum alloy products are divided into seven kinds of aluminum alloys, such as LF, LY, LD, LC, LB, LT and brazing (LQ). Aluminum alloy products are divided into:

The 1 system is 1000 aluminum, which is more than 99% of aluminum and is called pure aluminum. The price is lower than that of the 3 series aluminum, which is about 2000 yuan / ton, and the corrosion resistance is poor. The 3 line 3000 aluminum alloy is manganese aluminum alloy, which has better performance and higher price. The 5 line 5000 aluminum alloy is magnesium aluminum alloy, which has the best performance and the price is higher than that of the 3 aluminum alloy. (3 and 5 series aluminum is commonly called antirust aluminum, widely used in building exterior wall, such as aluminum curtain wall, plastic aluminum plate, etc.) 6 system 6000 aluminum alloy is magnesium silicon aluminum alloy, commonly known as forged aluminum; the price is 3000 yuan / ton.1 of aluminum lower than 3000 aluminum. The aluminum section is 6 series aluminum, it must be formed by anodizing the protective film - the thickness and firmness of the oxide film is the wear resistance of aluminum. The key to corrosion resistance. 2) 6 series aluminum is not suitable for making rainwater pipes, and the 6 aluminum is not rust proof unless the inner wall of the tube is made anticorrosive or paint treated.

The specific meaning and difference of aluminum number:

1 Series (pure aluminum, aluminum content not less than 99%)

2 series (mainly copper alloy)

3 Series (mainly with manganese)

4 series (mainly silicon)

5 Series (mainly with magnesium)

6 Series (mainly with magnesium and silicon)

7 Series (mainly zinc)

8 series (other elements)

A.1000 series represents 1050106010701000 series of aluminum plates, also known as pure aluminum plates. In all series, the 1000 series belong to a series of aluminum containing most. The purity can reach more than 99%. Because there are no other technology elements, so the production process is relatively simple, and the price is relatively cheap, which is the most commonly used series in the conventional industry. At present, most of the market circulation is 1050 and 1060 series. The 1000 series of aluminum plates, based on the last two Arabia figures, determine the minimum amount of aluminum in this series, such as the last two in the 1050 series and the Arabia number of 50. According to the international brand name principle, the content of aluminum must be up to 99.5% to be a qualified product. The aluminum alloy technical standard (gB/T3880-2006) of our country also clearly stipulates that 1050 aluminum content reaches the same principle of 99.5%., the aluminum content of the 1060 series aluminum plate must reach more than 99.6%.


Two 2000 series of aluminum plates represent 2A16 (LY16) 2A06 (LY6) 2000 series of aluminum plates with high hardness, with the highest copper content, about 3-5%. The 2000 series aluminum plates belong to aviation aluminum, which are not usually applied in conventional industries. At present, there are few factories producing 2000 series aluminum plates in China. The quality is not yet comparable to that of the foreign countries. At present, the imported aluminum boards are mainly provided by Korean and German manufacturers. With the development of China's aerospace industry, the 2000 series of aluminum plate production technology will further improve.

Three 3000 series of aluminum plates represent 30033003 3A21. It can also be called rust proof aluminum plate. The 3000 series aluminum plate production technology is excellent in China. The 3000 series of aluminum plates are composed of manganese elements. The content is between 1.0-1.5. It is a series of good antirust functions. Conventional applications in the air conditioning, fridge, car bottom and other wet environment, the price is higher than the 1000 series, is a more commonly used alloy series.

Four, the 4000 series aluminum plate is represented by 4A01 4000 series aluminum plate, which belongs to a series of high silicon content. The content of silicon is usually between 4.5-6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials, low melting point, corrosion resistance, product description: it has the characteristics of heat resistance and wear resistance.

The five 5000 series represents the 5052.5005.5083.5A05 series. The 5000 series aluminum plates belong to the more commonly used aluminum alloy 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 characteristics are low density, high tensile strength and high elongation. Under the same area, the weight of Al Mg alloy is lower than that of other series. So it is usually used in aviation, such as aircraft fuel tank. It is also widely used in the conventional industry. The processing technology is continuous casting and rolling. It belongs to the series of hot rolled aluminum plates, so it can do deep oxidation processing. In China, the 5000 series aluminum plate is one of the more mature aluminum plate series.

Six 6000 series representative 6061 mainly contain two elements of magnesium and silicon, so the advantage of 4000 series and 5000 Series is 6061 is a cold - treated aluminum forging product, which is suitable for the application of high corrosion resistance and high oxidation. It has good usability, excellent interface characteristics, easy coating and good processability. It can be used on low pressure weapons and aircraft joints.

6061, the general characteristics are excellent interface features, easy coating, high strength, good usability and strong corrosion resistance.

6061 typical uses of aluminum: aircraft parts, camera parts, couplers, ship fittings and hardware, electronic fittings and joints, decorative or various hardware, hinges, magnetic heads, brake pistons, water pistons, electrical fittings, valves, and valve parts.

Seven 7000 series representative 7075 mainly contain zinc. Also belong to the aviation series, aluminum, magnesium, zinc and copper alloy, heat treatment alloy, super hard aluminum alloy, good wear resistance.7075 aluminum plate is to eliminate stress, no deformation, warp after processing. All super thick 7075 aluminum plate all through ultrasonic detection, can ensure that no sand, impurity.7075 aluminum plate high thermal conductivity, can shrink Short forming time, improve work efficiency. The main feature is hardness, big 7075, high hardness and high strength aluminum alloy. It is used to make aircraft structure and futures. It requires high stress and high corrosion resistant structural parts and dies. At present, basically rely on imports, China's production technology needs to be improved.
