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.

Q:What is the difference between aluminum plate and aluminum-plastic plate?
The difference is as follows: 1, different layers: single aluminum plate is divided into two layers, the surface layer is aluminum skin, second layers of plastic, aluminum plate is divided into three layers: the surface layer and the third layer is an aluminum sheet, the middle is plastic, or aluminum plate than single aluminum plate a layer of aluminum skin; 2, the quality of different because: aluminum sheet aluminum plastic board less than a layer of aluminum skin, so the single aluminum plate than the aluminum plate quality will certainly be worse; 3, the price is different: single aluminum plate is cheaper than aluminum plate, aluminum plate positioning for low-grade, aluminum-plastic plate according to the quality and thickness of plastic and aluminum skin into the middle different grades, but certainly more than the single aluminum plate and expensive; 4, the construction effect is certainly not the same: a plastic plate can be slotted, bending turning construction construction, suitable for a variety of occasions, but not the single aluminum plate slot, bending, and because the bottom is plastic, such as plastic bonding effect Board.
Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
Q:What are the aluminum plates for?
Defense (cover containing polyethylene moistureproof layer of kraft paper embossing aluminum alloy), special mould. The tensile aluminum alloy aluminum coated aluminum. Special stamping. Electronic gasket aluminum, alloy aluminum alloy electric radiator. Special aluminum curtain wall coating. (fluorocarbon, polyester) aluminum coil, aluminum coil, special signs aluminum plate, color coated aluminum sheet, aluminum ceiling coating, aluminum plate, aluminum plate pattern, embossing aluminum / aluminum (pointer type, orange peel pattern, diamond, five ribs, aluminum strip). Aluminum wire and cable, transformer Using aluminum strip, aluminum foil, pressure type aluminum corrugated corrugated aluminum plate. Color coating, special aluminum plate, aluminum plate cable tray, material: 1100.1200.1050A.1060.1070.1080.1145.2A11.3003.3A21.3004.3005.3104.3105.LF21.5A02.5A05.5005.5754.5052.5083.5082.5A03.6061.6063.6082.8011. material; H111.H112.H18.H26.H16.H22.H32.H34.H36.H14.H24.H12.T4.T5.T6.O.F state can meet the requirements of customers
Q:what will happen when aluminum sheet is put into copper chloride solution?
the chemical equation of the reaction, 2Al+3CuCl2=2AlCl3+3Cu, the phenomena when aluminum sheet is put into copper chloride solution: there is red solid generating on the surface of aluminum sheet.
Q:Aluminum plate 90 degree bending, why cracking?
Should be the aluminum sheet material and status is wrong, I wonder what brand aluminum plate?.Use 1060 Aluminum plate, condition: soft, 90 degree bending, won't crack
Q:What will affect the performance of the aluminum ingot in the process of casting?
There are two major types of aluminum ingot after industrial application: cast aluminum alloy and wrought aluminum alloy. Cast aluminium and aluminum alloy are used to produce aluminium castings by casting method. Wrought aluminium and aluminium alloy are produced by pressure process. They are plates, belts, foils, tubes, rods, shapes, wires and forgings. According to the national standard "aluminum ingots for remelting by chemical composition is divided into 8 grades, namely Al99.90, Al99.85, Al99.70, Al99.60, Al99.50, Al99.00, Al99.7E, Al99.6E" (Note: Al number is aluminum content). Some people call "A00" aluminum, in fact, is aluminum containing 99.7% purity aluminum, called standard aluminum in the London market".
Q:Aluminum plate belongs to steel or non ferrous metal?
Metal materials fall into two broad categories: ferrous and non-ferrous metals. What we usually call "iron and steel" is ferrous metal; copper and aluminum are nonferrous metals.
Q:Are there any rules and requirements for the spacing between the back of the glass curtain wall and the aluminum plate and the glass?
Thermal explosion is related to a lot of factors. As to how much impact the lining board has on the thermal explosion, it's really impossible to speak of it. I think it has very little influence
Q:why does the bubble apear a few minutes later after putting aluminum sheet into dilute sulphuric acid?
Because there is oxide on the surface of aluminum, the reaction will be quicker after polishing the oxide with abrasive paper.
Q:8mm which type of aluminum plate is suitable for bending?
How do I calculate the pressure of the seamless steel tube with the outer diameter of 300mm and the thickness of 18mm L=600mm? material
