Aluminum square bar is a kind of aluminum bar. Aluminum square bar is a long bar with a square cross section. It is divided into extruded aluminum alloy square bar, drawn square aluminum bar, and cut aluminum square bar.
Side lengt h: 6.3mm~250mm, the size can be customized according to user requirements.
Length: 2500mm, 3000mm, 6000mm, can be cut according to customer requirements.
Surface treatment: polished aluminum square bar, drawn aluminum square bar, oxidized square aluminum bar, etc.
Meter weight (kg)= side width (mm) x side width (m) x length (m) x 2.7g/cm3
(LME ingot price + processing fee) x weight + packing fee + shipping fee

If you find the aluminum price every day, please contact Chalco aluminum to inquire about the price, and ask about the processing fee per ton of the relevant type of aluminum square bar. Different alloys have different processing fees, and the difference is quite large. We will provide you with the best quotation.
Alloy: 1050, 1060, 1070, 1100 aluminum square bar
Physical property: Contains more than 99.00% aluminum. Since it does not contain other technical elements, the production process is relatively simple, the price is relatively cheap. It has the properties of good electrical conductivity, good corrosion resistance, good welding performance, low strength, and cannot be strengthened by heat treatment.
Application: Mainly used for transformer conduction, anti-corrosion chemical industry and special purpose.
Chalco Aluminum hot selling products: 1070 H112 Conductive Square Aluminum bar.
Alloy: 2A12, 2014, 2024, 2011, 2017 aluminum square bar
Temper: T3, T4, T351, T6, T6511
Physical property: The aluminum alloy containing copper as the main alloying element. It may also add manganese, magnesium, lead and bismuth at about 3-5% for machinability and high hardness.
Application: It belongs to aviation aluminum, and mainly used in the aviation industry such as aviation industry (2014 aluminum square bar), screws (2011 aluminum square bar) and industries with high service temperature (2017 aluminum square bar). But it is not commonly used in conventional industries.
Chalco Aaluminum hot selling products: 2024 T4 T351 aluminum square bar, after heat treatment (T3, T4, T351), the mechanical properties are significantly improved.
T3 state parameters: tensile strength 470MPa, 0.2% yield strength 325MPa, elongation 10 %, fatigue strength 105MPa, hardness 120HB.
Alloy: 3003, 3A21 aluminum alloy square bar
Temper: H112, H24
Physical property: Manganese is the main alloy component, the content is between 1.0-1.5. It has good corrosion resistance and good welding performance. The disadvantage is that the strength is low, but the strength can be strengthened by cold work hardening. Coarse grains are easily pbaruced during annealing.
Alloy: 4A01 aluminum alloy square bar
Temper: H112, F
Physical property: Usually the silicon content is between 4.5-6.0%, mainly silicon. It has the properties of thermal expansion coefficient, easy to cast, low melting point, good corrosion resistance, heat resistance and wear resistance. The less or higher silicon content will affect its performance.
Applications: construction materials, mechanical parts, forging materials, welding materials, pistons and cylinders of motor vehicles, etc.
Alloy: 5052, 5005, 5083, 5A05, 5A06 aluminum alloy square bar
Temper: H112, F
Physical property: The main element is magnesium, with the content between 3-5%. It has the physical properties of medium strength, good corrosion resistance, good welding performance, good process performance, good oxidation coloring performance, low density, etc. In the same area, the weight of aluminum magnesium alloy is lower than that of other series. The fatigue strength is good and it cannot be strengthened by heat treatment, but can only be improved by cold working.
Applications: lawn mower handles, aircraft fuel tank conduits, body armor, military industry.
Chalco Aaluminum hot selling products: 5083 H112 Marine Square Aluminum bar.
Alloy: 6061, 6063, 6082, 6060 aluminum alloy square bar
Physical property: It mainly contains magnesium and silicon, so it combines the advantages of 4000 series series and 000 series series, medium strength, good corrosion resistance, good welding performance, good process performance, and good oxidation coloring performance.
Application: currently the most widely used alloy, energy transfer tools, marine aluminum square bar (such as car luggage rack, door, window, body, heat sink, box shell).
Alloy: 7075, 7050, 7A04 aluminum alloy square bar
Physical property: It mainly contains zinc element. It is an aluminum-magnesium-zinc-copper alloy and also belongs to the aviation series. It is a heat-treatable alloy, and belongs to a superhard aluminum alloy with good wear resistance.
Application: 7A04 aluminum square bar, used for screws, and stressed components such as girder stringers, bulkheads, wing ribs, landing gear, etc., 7075 high-stress structural parts, mold manufacturing.
Aluminum ingots, magnesium and other metals are added to the melting furnace according to the proportion to obtain aluminum liquid, and the aluminum liquid is passed through the casting process to obtain aluminum round bars of different specifications.
According to the aluminum square bar dies with different sizes and cross-sections, the aluminum round bar are extruded into finished aluminum square bar of different specifications.
2000 series, 6000 series, 7000 series aluminum square bars need super cooled water quenching to get higher strength. 1000 series, 3000 series, 5000 series, 4000 series aluminum square bars generally do not need quenching.
For the aluminum square bar with high tolerance requirements and straightness requirements, it needs to be drawn to correct the straightness and release the internal stress. The strength of the aluminum bar is higher, and the usual state is T6511.
The extruded aluminum square bar needs to be straightened. The straightness of the aluminum square bar affects whether it can be used on mechanical equipment, so the straightness of the aluminum square bar meets the standard, which is one of the important standards for the quality of the aluminum square bar.
The surface can be treated by anodizing, spraying, drawing, grinding and so on.
Aluminum square bar are cut into certain lengths according to customer requirements.
