Product Description:

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:In cutting aluminum rods, the teeth of the disc saw are occasionally knocked out. How can they be avoided?
The melting point of aluminum is low, easy to stick knife, plus cooling liquid can be solved
Q:I do lathe processing, how to make 6061 of the aluminum bars crisp, or what good processing methods?
The groove must be smooth. In addition jiaqie chip liquid is the key, of course, is the best add oil.
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:Remelted scrap aluminium alloy window aluminum rod of 1 tons can sell how much money.
Alloy furnace: iron is the harmful substance in aluminum and its alloy, and it has the greatest influence on the mechanical properties of aluminum alloy. Therefore, the scrap iron in miscellaneous aluminium should be selected in the pretreatment process to the maximum extent. By separating the magnetic separation of iron and steel scrap and further processing, because there are combined mechanical parts of aluminum based non-ferrous metal scrap iron and steel in some devices, it is difficult to separate, such as nuts, scrap pieces of wires, keys, plumbing parts, small gear, it is necessary for the separation of this part, because separation of nonferrous metals can improve and enhance the value of scrap iron and steel grades, but the separation is difficult, generally use the manual dismantling and sorting, but low efficiency. In order to improve the production efficiency, the most effective way to deal with the difficult to disassemble parts of aluminum and steel is to heat them in a special melting furnace to make the aluminum melt out of the waste steel.Casting homogenizing furnace: controlling the quality of aluminium profile by controlling the alloy composition of aluminium ingot. Adopting the advanced proportional heating and temperature control system, the temperature difference is small, the casting adaptability and component segregation of the aluminum rod are eliminated completely, and the plasticity and the strength of the alloy are greatly improved.
Q:Why should two two iron bars and two aluminum rods be used in a water heater?
Iron is used to dissolve iron ions into water, so that the water appears to be of different colors.Aluminum is used to coagulate and cause flocculation and turbidity in the water.
Q:Why is the temperature of the extrusion cylinder lower than the aluminum bar and die temperature?
The casting process of aluminum bars includes melting, purification, impurity removal, degassing, slag removal and casting process. The main process is: (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: adding the raw material to the melting furnace according to the process requirements, and through degassing and removing
Q:The aluminum bar has a wavy bend. What's the matter? 5
Extruded products rarely have straight, which have a relationship with mold, quenching, traction and cooling system. After production, you can straighten it with the drawing machine.
Q:What is an aluminum rod intermediate frequency heating furnace?
The aluminum rod intermediate frequency heating furnace is a kind of aluminum rod heating furnace for extrusion. It is suitable for heating larger diameter aluminum bars. The heating speed is fast and the temperature control is more accurate.
Q:The difference between aluminium bars 6061a and 6061
In the same way, they are attributed to high strength hard aluminium. 2A12 aluminum bars are a kind of high strength hard aluminium, which can be enhanced by heat treatment.
Q:What are the diameters of the aluminum bars sold on the market?
Then, more than 200mm is basically a cast aluminum bar.The tube can also be made of aluminium tube, the price is almost the same as the aluminum bar, and the right size can be saved.
