Product description:
Aluminium Flat Bar is extremely versatile and available in a range of sizes for any application.Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).
The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.
One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.
Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.
The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.
Another alloy of some value is aluminium bronze (Cu-Al alloy).
Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.
Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.
Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.
Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.

Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.The chief ore of aluminium is bauxite.
Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.
Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.
The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."
Davy settled on aluminum by the time he published his 1812 book Chemical Philosophy: "This substance appears to contain a peculiar metal, but as yet Aluminum has not been obtained in a perfectly free state, though alloys of it with other metalline substances have been procured sufficiently distinct to indicate the probable nature of alumina."[69] But the same year, an anonymous contributor to the Quarterly Review, a British political-literary journal, in a review of Davy's book, objected to aluminum and proposed the name aluminium, "for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound."
The -ium suffix conformed to the precedent set in other newly discovered elements of the time: potassium, sodium, magnesium, calcium, and strontium (all of which Davy isolated himself). Nevertheless, -um spellings for elements were not unknown at the time, as for example platinum, known to Europeans since the 16th century, molybdenum, discovered in 1778, and tantalum, discovered in 1802. The -um suffix is consistent with the universal spelling alumina for the oxide (as opposed to aluminia), as lanthana is the oxide of lanthanum, and magnesia, ceria, and thoria are the oxides of magnesium, cerium, and thorium respectively.
The aluminum spelling is used in the Webster's Dictionary of 1828. In his advertising handbill for his new electrolytic method of producing the metal in 1892, Charles Martin Hall used the -um spelling, despite his constant use of the -ium spelling in all the patents[58] he filed between 1886 and 1903. It has consequently been suggested[by whom?] that the spelling reflects an easier-to-pronounce word with one fewer syllable, or that the spelling on the flyer was a mistake.[citation needed] Hall's domination of production of the metal ensured that aluminum became the standard English spelling in North America.
- Q: Is the elongation of aluminum bars related to the diameter?
- The elongation rate (delta) is described, elongation and section shrinkage index psi plastic properties. Elongation is the percentage of the total deformation L of the gauge section and the ratio of the original distance to the length L after the tensile fracture of the specimen.
- Q: How do we pay taxes on the export of raw materials and aluminum rods in the near future? As a matter of fact, we export some aluminum bars and need to pay export duties. I would like to ask: 1. export tariffs how to calculate it? We are trading companies, for example, we purchased 20 yuan / kg, profit: 2 yuan / kg. HS code:7604291099 export tariff rate is: 5%. Freight, customs and so on 1000 yuan. The total quantity is 1000 kilograms. What is the unit price I quoted? How much is the tax (per kilogram)? 2., how to pay export tariffs, is the customs declaration link? The more detailed, the better, thank you. Export duty
- It is common sense to import taxes and export rebates.Export tariffs are returned and no tax is paid. Examples: pesticidesCommodity code 3808911900Other brands of pesticide used in retail packagingTax rate informationMeasurement unit kgPreferential import tax rate of 10%Export tax rate 0%VAT 13%Provisional tax rateGeneral rate of import 35%Export tax rebate rate 5%The export tax rebate rate here is what the country refunded to you, so we must make it clear that only the import will pay taxes!
- Q: What is the deformation temperature of the aluminum rod mold?
- It depends on the requirements of your equipment (imported or domestic) and refining the main function of control, there is a guarantee to improve the quality of continuous casting measures, such as the need of EMBR EMS mold expert system, all your requirements are not the same, the price difference is certainly much worse, I suggest you can design consulting institute the relevant information related to go directly to.
- Q: Our company needs to make the aluminum bar 10 in diameter to be "U", which is done by hand, which is slow. Where is there such a bending device, or is it a fully automatic equipment?
- Ha ha, tell you there is a reward? 10 of the aluminum rod diameter is very small, you can consider using bending machine, or combined punching and shearing machine, punching machine or automatic equipment, how do you want to fully automatic method, to 6 meters of raw materials made directly over U segments, such a down nearly 100 thousand.
- Q: Aluminum bars 5000 and imported aluminum rods 7075 which is good corrosion resistance?
- The 5000 Series is AL-Mn alloy, is one of the most widely used aluminium alloy, the strength is high, especially with anti fatigue strength: ductility and high corrosion resistance, heat treatment can strengthen, in the semi cold hardening plastic plastic is good, low cold hardening, resistance good corrosion, good weldability, machinability, polishing.
- Q: Numerical control car 8mm aluminum bar material 3003, with what blade feeding speed, how much speed, cutting quantity for big master answer
- I feel this speed can be done with high speed steel tools;You follow; the speed at about 1500; feed in 0.1. cut deep or 0.5mm or so; try; this surface quality is bad, drop feed; blade go to the market looking for aluminum blade; sharp point, don't coating.
- Q: Aluminum bars refer to extruded aluminum bars, and I would like to know which areas of aluminum bar profiles are used, and what are the more influential customers in various fields
- Look at South South aluminum and Huayin Aluminum clients (Debao).
- Q: 3050mm or 60mm large aluminum bar, punch out 8mm long, can you do this? The section is required to be smooth, can you do this?Why can't you always?50mm is diameter and ~~~~~~8mm is thickness
- Do you want to cut long aluminum bars into 8mm lengths or to cut 50mm or 60mm large aluminum bars into 8mm thickness? Please indicate white spots. If it is cut into 8 of the length, it can be done without punching machine, very simple cutting.
- Q: The difference between die cast aluminum and extruded aluminium rods
- The casting process of aluminum bars includes melting, purification, impurity removal, degassing, slag removal and casting process:(1) batching: according to the needs of the production of specific alloy grade, calculated the addition of various alloy ingredients, reasonable collocation of various raw materials(2) melting: the raw material is added into the melting furnace according to the process requirements, and the impurity and gas in the melt can be removed effectively by means of degassing and slag refining(3): casting aluminum liquid in melting casting process under certain conditions, through deep casting system, cooling cast into various specifications of the round casting rod.
