The most complete classification of aluminum profile numbers1

Do you have any questions about the model of aluminum profile? We have prepared the most complete model reference for you, from which you can understand the corresponding models and uses, such as c profile aluminum, profile 6 20x80 and so on.

According to the different content of alloying elements, aluminum plates can be divided into 8 series:

1XXX pure aluminum series 99.00% or more
2XXX Al-Cu
3XXX Al-Mn
4XXX Al-Si
5XXX Al-Mg
6XXX Al-Mg-Si
7XXX Al-Zn
Systems other than the previous code name 8XXX

Typical use of aluminum alloy

1050 Extrusion coils for food, chemical and brewing industries, fireworks powder, various hoses
1060 Where high corrosion resistance and formability are required, but the strength requirements are not high, chemical equipment is its typical use
1100 is used for processing parts that require good formability and high corrosion resistance but do not require high strength, such as chemical products, food industry equipment and storage containers, thin plate processing parts, deep drawing or spinning concave vessels, Welding parts, heat exchangers, printed boards, nameplates, reflectors
1145 Packaging and insulation aluminum 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 Used in occasions requiring high strength and hardness (including high temperature). Aircraft heavy-duty, forgings, thick plates and extruded materials, wheels and structural elements, multi-stage rocket first-stage fuel tanks and spacecraft parts, truck frames and suspension system parts
2017 is the first 2XXX series alloy to obtain industrial application. The current application range is relatively narrow, mainly for rivets, general mechanical parts, structural and transportation structural parts, propellers and accessories
2024 aircraft structure, rivets, missile components, truck hubs, propeller components and other various structural parts
2036 car body sheet metal parts
2048 Aerospace vehicle structural parts and weapon structural parts
2124 Aerospace Vehicle Structural Parts
2218 aircraft engine and diesel engine piston, aircraft engine cylinder head, jet engine impeller and compressor ring
2219 Space rocket welding oxidant tank, supersonic aircraft skin and structural parts, working temperature is -270~300℃. Good weldability, high fracture toughness, T8 state has high resistance to stress corrosion cracking
2319 Welding electrode and filler solder of 2219 alloy
2618 Die forgings and free forgings. Pistons and aero engine parts
2A01 Structural rivets with working temperature less than or equal to 100℃
2A02 Axial compressor blades of turbojet engines with working temperature of 200~300℃
2A06 Rivets for aircraft structures with operating temperature of 150~250℃ and aircraft structures with operating temperature of 125~250℃

The strength of 2A10 is higher than that of 2A01 alloy. It is used to manufacture aircraft structural rivets whose working temperature is less than or equal to 100°C.

2A11 Medium-strength structural parts of aircraft, propeller blades, transportation vehicles and building structural parts. Medium-strength bolts and rivets for aircraft
2A12 Aircraft skins, bulkheads, wing ribs, wing beams, rivets, etc., construction and transportation tool structures
2A14 Free forgings and die forgings with complex shapes
2A16 Aerospace parts with working temperature of 250~300℃, welding vessel and airtight cockpit working at room temperature and high temperature
2A17 Aircraft parts with operating temperature of 225~250℃
2A50 Medium-strength parts with complex shapes
2A60 aircraft engine compressor wheel, wind deflector, fan, impeller, etc.
2A70 Aircraft skins, aircraft engine pistons, wind deflectors, roulettes, etc.
2A80 aero engine compressor blades, impellers, pistons, expansion rings and other parts with high working temperature
2A90 Aero Engine Piston
3003 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 products processing And storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes made of thin plates
The body of 3004 all-aluminum cans requires higher-strength parts than 3003 alloy, chemical product production and storage devices, thin plate processing parts, construction processing parts, construction tools, and various lighting components.
3105 Room partitions, baffles, movable house boards, gutters and downpipes, thin plate forming parts, bottle caps, bottle stoppers, etc.
3A21 Aircraft fuel tanks, oil ducts, rivet wires, etc.; industrial equipment such as building materials and food
