Knowledge about 1000-9000 Series Aluminum Alloy
Aluminum alloy is composed of aluminum as matrix element and alloy with one or more alloying elements.
The main alloying elements are copper, silicon, magnesium, zinc, manganese, and secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc. Aluminum alloy is one of the most widely used nonferrous metal structural materials in industry, which has been used extensively in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Aluminum alloy density is low, but the strength is higher, close to or more than high-quality steel, good plasticity, can be processed into a variety of profiles have excellent conductivity, thermal conductivity and corrosion resistance, industrial widely used, the use of the volume after the iron.
According to the alloying element content different aluminum alloy may divide into 9 Series, they are 1***,2***,3***,4***,5***,6***,7***,8***,9***.
1*** Series：1000 Series aluminum alloy represents 1050, 1060, 1100 series. In all series, the 1000 series belongs to a series with the most aluminum content. The purity can reach more than 99.00%.
2*** Series：2000 series aluminum alloy represents 2024, 2a16 (LY16), 2A02 (LY6). 2000 series of aluminum plate is characterized by high hardness, of which the highest content of copper, probably around 3-5%. The 2000 series aluminum rods belong to aviation aluminum, which is not often used in conventional industry.
3*** Series：3000 Series aluminum alloy represents 3003, 3A21 mainly. China 3000 series Aluminum sheet production process is more excellent. The 3000 series aluminum rods are mainly composed of manganese elements. Content between 1.0-1.5, is a good anti-rust function series.
4*** Series：The 4000 series aluminum rods represent the 4A01 4000 series of aluminum plates that belong to a high silicon content series. Usually the silicon content is between 4.5-6.0%. is a building materials, mechanical parts forging material, welding materials; Low melting point, good corrosion resistance, heat resisting and wear-resistant.
5*** Series：5000 Series aluminum alloy represents 5052, 5005, 5083, 5A05 series. 5000 Series Aluminum rods belong to more commonly used alloy aluminum plate series, the main elements are magnesium, magnesium content between 3-5%. It can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength, high elongation, good fatigue strength, but can not be enhanced by heat treatment. Under the same area the weight of Al-Mg alloy is lower than that of other series. It is widely used in conventional industry. In our country 5000 series aluminum sheet belongs to the mature aluminum plate series one.
6*** Series：6000 Series aluminum Alloy representative 6061 mainly contains magnesium and silicon two elements, so concentrated 4000 series and 5000 series of advantages 6061 is a cold treatment of aluminum forging products, applicable to resist corrosion, oxidation of the application of high requirements. Good usability, easy coating, good processability。
7*** Series：7000 Series aluminum alloy representative 7075 mainly contains zinc element. Also belongs to the aviation series, is the aluminum magnesium zinc copper alloy, is the heat-treatable alloy, belongs to the superhard aluminum alloy, has the good abrasion resistance. Also has the good weldability, but the corrosion resistance is poor.
8*** Series：8000 Series aluminum alloy is more commonly used for 8011 belong to other series, most of the application for aluminum foil, the production of aluminum rods is not very common.
9*** Series：The 9000 series aluminum alloy is a standby alloy.
