Code | Name | Description and Application |
1xxx | 1 grade aluminium alloy | 1xxx series with low density. The specific gravity of pure aluminum is 2.71. Under the same volume, the weight of the 1 series aluminum plate is only 35% of iron. High-purity aluminum (aluminum content above 99.9%) is mainly used in scientific experiments, chemical industry, chemical equipment, inland watercraft equipment, various containers (wine tanks, pressure tanks, tea stoves, etc.), conductive materials, chemical equipment, Instruments and meters, signs (equipment signs, road signs, motor vehicle license plates, etc.), building decoration materials, hardware cooking utensils, machine parts with little force. It is applied to products that do not require high strength, such as chemical instruments, thin-sheet processed parts, deep-drawn or spinning concave vessels, welded parts, heat exchangers, clock surfaces and disc surfaces, nameplates, kitchenware, decorations, reflective appliances, etc. |
2xxx | 2 grade aluminium alloy | The 2xxx series are heat-treatable,and possess in individual alloys good combinations of high strength (especially at elevated temperatures),toughness,and,in specific cases, weldability;they are not resistant to atmospheric corrosion,and so are usually painted or clad in such exposures.2xxx aluminium is mainly used in applications requiring high strength and hardness (including high temperature). Aircraft heavy, forged, thick and extruded materials, wheels and structural components, first stage fuel tank and spacecraft parts of multi-stage rocket, truck frame and suspension system parts. |
3xxx | 3 grade aluminium alloy | 3XXX series are AL-Mn series alloys, which are the most widely used anti-rust aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are used to improve its mechanical properties. : High plasticity in the annealed state, good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, and poor machinability. Uses are mainly used for low-load parts that require high plasticity and good weldability and work in liquid or gaseous media, such as mailboxes, gasoline or lubricating oil pipes, various liquid containers and other small-load parts made by deep drawing: The wire used to make rivets 3XXX series aluminum plate has good formability, weldability and corrosion resistance. It is used for processing parts that require good formability, high corrosion resistance and good weldability, or work that requires these properties and requires higher strength than 1XXX series alloys, such as kitchenware, food and chemical product processing and Storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes made of thin plates, general utensils, heat sinks, makeup boards, photocopier drums, and ship materials. |
5xxx | 5 grade aluminium alloy | The main ingredient of 5 series aluminum alloy is magnesium element and the content is between 3% and 5%. It is also called aluminum magnesium alloy.With its low density, it features high tensile strength and elongation.With the same area of other series, the weight of this aluminum plate is lighter. As a result, it is used in aviation, such as in the fuel tanks in airplanes, pressurised vessels, buildings and automotive |
6xxx | 6 grade aluminium alloy | 6 Series aluminum is characterized by: medium strength, good plasticity and excellent corrosion resistance. In particular, stress corrosion cracking tendency, its excellent weldability, corrosion resistance and cold workability, is a wide range of uses. Such as window and door parts, architectural applications, hardware, furniture parts, rings, fuses, electrical conductors, screw machine parts |
7xxx | 7 grade aluminium alloy | The 7xx.x aluminum-zinc-magnesium alloys are notable for their combinations of good finishing characteristics, good general corrosion resistance, and the capability of developing high strength through natural aging without heat treatment.7xxx series alloys are used in airframe structures, mobile equipment, and other highly stressed parts. |
8xxx | 8 grade aluminium alloy | The more commonly used 8XXX series is 8011, which belongs to other series. Series 8 aluminum foil has excellent sealing, plasticity, and antifouling.propertiesAluminum foil is a non-toxic packaging material and the surface of the aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can grow on its surface. |
