In short, aluminum profile is an application product form of aluminum alloy, and aluminum alloy belongs to aluminum material. Aluminum alloy materials or pure aluminum materials can be called aluminum profiles.
Aluminum alloy is mainly composed of aluminum, which is an alloy of various metal elements such as silicon, copper, zinc, magnesium, manganese, iron, titanium, chromium, nickel, etc. It is an alloy of non-ferrous metals. A sort of. In addition to aluminum alloys, there are pure aluminum (only when the aluminum content is more than 99%) and 1-8 series aluminum alloys.
It is customary to say that aluminum materials or pure aluminum materials can be called aluminum materials; common aluminum materials include aluminum plates, aluminum doors and windows, aluminum ceilings, aluminum curtain walls, aluminum profiles, and aluminum castings (automotive engines, etc.) And space shuttle accessories, mechanical accessories, electronic and electrical accessories, etc. have the shadow of aluminum.
To sum up, as the name suggests, aluminum is a kind of material, and aluminum alloy is a kind of metal.
Classification is different:
Aluminum alloys are classified according to the production process. Features:
Series 1: Features: Contains more than 99.00% aluminum, good electrical conductivity, good corrosion resistance, good welding performance, low strength, and cannot be strengthened by heat treatment. Testing, chemical industry and special purposes.
Series 2: Features: Aluminum alloys with copper as the main element. Manganese, magnesium, lead and bismuth are also added for machinability. Such as: 2011 alloy, pay attention to safety protection during the smelting process (harmful gas will be generated). The 2014 alloy is used in the aerospace industry and has high strength. The 2017 alloy is a little less strong than the 2014 alloy, but easier to machine. 2014 can be heat treated to strengthen. Disadvantages: Severe intergranular corrosion tendency. Application range: aviation industry (2014 alloy), screws (2011 alloy) and industries with high temperature (2017 alloy).
Series 3: Features: The aluminum alloy with manganese as the main alloying element cannot be strengthened by heat treatment, and has good corrosion resistance and good welding performance. Good plasticity. (closer to super-aluminum alloy). Disadvantages: Low strength, but can be strengthened by cold work hardening. Coarse grains are easily generated during annealing. Scope of application: seamless oil-guiding pipes (3003 alloy) used in aircraft, cans (3004 alloy).
4 series: mainly silicon, not commonly used. Some 4-series alloys can be strengthened by heat treatment, but some 4-series alloys cannot be heat-treated. hr
5 series: Features: mainly magnesium. Good resistance performance, good welding performance, good fatigue strength, can not be strengthened by heat treatment, only cold working can improve the strength. Applications: lawn mower handles, aircraft fuel tank conduits, body armor.
6 series: Features: mainly magnesium and silicon. Mg2Si is the main strengthening phase and is currently the most widely used alloy. 6063, 6061 are used most, other 6082, 6160, 6125, 6262, 6060, 6005, 6463. 6063, 6060, and 6463 have relatively low strength in the 6 series. 6262, 6005, 6082, and 6061 have relatively high strength in the 6 series. Features: medium strength, good corrosion resistance, good welding performance, good process performance (easy to extrude and form), good oxidation and coloring performance. Scope of application: energy transfer tools (such as: car luggage racks, doors, windows, body, heat sinks, compartment shells)
Series 7: Features: Mainly zinc, but sometimes a small amount of magnesium and copper are added. Among them, superhard aluminum alloys contain zinc, lead, magnesium and copper alloys that are close to the hardness of steel. The extrusion speed is slower than that of the 6 series alloy, and the welding performance is good. 7005 and 7075 are the highest grades in the 7 series and can be heat treated to strengthen. Scope of application: aviation (airplane bearing components, landing gear), rockets, propellers, aerospace.
Aluminum profiles are classified features:
(1)According to surface treatment requirements
(1) Anodized aluminum
(2) Electrophoretic painted aluminum
(3) Powder coating aluminum
(4) Fluorocarbon paint sprayed aluminum
(5) Wood grain transfer aluminum
(2)According to the alloy composition,
aluminum is divided into pure aluminum and aluminum alloy. Aluminum alloys are divided into Al-Mn alloys, Al-Cu alloys, Al-Si alloys and Al-Mg alloys according to the alloy series.
(3)According to the pressure processing ability,
it can be divided into deformed aluminum and non-deformed aluminum (for example: cast aluminum).
