Aluminum profile classification method
First, according to the use can be divided into the following categories:
1. Architectural aluminum profiles (divided into doors and windows and curtain walls).
2. Radiator aluminum profiles.
3. General industrial aluminum profiles: mainly used in industrial production and manufacturing, such as automated mechanical equipment, enclosure skeletons and various companies to customize molds according to their own mechanical equipment requirements, such as assembly line conveyors, hoists, dispensers, Testing equipment, shelves, etc., the electronic machinery industry and clean rooms are mostly used.
4. Rail vehicle structure Aluminum alloy profiles: mainly used for the manufacture of rail vehicle bodies.
5. Mounted aluminum profiles, made into aluminum alloy frame, decorated with various exhibitions and decorative paintings.
Second, according to the classification of alloys
Can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other alloy grade aluminum profiles, of which the 6 series are the most common. The difference between the different grades is that the ratio of various metal components is not the same, except for the commonly used aluminum alloy profiles Such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum profiles, industrial aluminum profiles have no clear model distinction, most of the production plants are processed according to the customer's actual drawings.
Third, the typical use of different grades of aluminum alloy
1050: Extrusion coils for food, chemical and brewing industries, various hoses, fireworks powder
1060: Where high corrosion resistance and formability are required, but the strength is not high, and chemical equipment is its typical use.
1100: For the processing of parts requiring good formability and high corrosion resistance but not requiring high strength, such as chemical products, food industry equipment and storage containers, sheet processing parts, deep drawing or spinning concave vessels , welding parts, heat exchangers, printing plates, nameplates, reflective appliances
1145: Packaging and insulation foil, heat exchanger
1199: Electrolytic capacitor foil, optical reflective deposition film
1350: wires, conductive strands, bus bars, transformer strips
2011: Screws and machined products requiring good cutting performance
2014: For applications requiring high strength and hardness (including high temperature). Aircraft heavy duty, forgings, slabs and extruded materials, wheels and structural components, multi-stage rocket first stage fuel tank and spacecraft parts, truck frame and suspension system parts
2017: It is the first 2XXX series alloy to obtain industrial applications. The current application range is narrow, mainly for rivets, general mechanical parts, structural and transportation structural parts, propellers and accessories.
2024: Aircraft structures, rivets, missile components, truck hubs, propeller components and other structural components
2036: Auto body sheet metal parts
2048: Aerospace structural components and weapon structural parts
2124: Aerospace structural components
2218: Aircraft and diesel engine pistons, aircraft engine cylinder heads, jet engine impellers and compressor rings
2219: Aerospace rocket welding oxidizer tank, supersonic aircraft skin and structural parts, operating temperature is -270 ~ 300 degrees Celsius. Good weldability, high fracture toughness, high resistance to stress corrosion cracking in T8 state
2319: Welding electrode and filler solder for welding 2219 alloy
2618: Die forgings and free forgings. Piston and aero engine parts
2A01: Structural rivet with working temperature less than or equal to 100 degrees Celsius
2A02: Axial compressor blades for turbojet engines operating at temperatures from 200 to 300 degrees Celsius
2A06: Aircraft structure with working temperature of 150~250 degrees Celsius and aircraft structure rivets with working temperature of 125~250 degrees Celsius
2A10: High strength compared to 2A01 alloy, used to manufacture aircraft structural rivets with working temperature less than or equal to 100 degrees Celsius
2A11: Medium-strength structural parts, propeller blades, transportation vehicles and building structural parts of the aircraft. Medium-strength bolts and rivets for aircraft 2A12 Aircraft skins, bulkheads, ribs, spars, rivets, etc., construction and transport structural components
