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.China Longbird Group is mainly engaging in coated aluminium coil, new construction material, education, automobile trade, machinery, general merchandise, real estate, investment, trade etc. The parent company is specialized in aluminium foil coating, which is the main material for the aluminium plastic composite panel. The aluminium plastic composite panel is a new kind composite panel based on coated aluminium coil panel and plastic panel. It centralize the merits of metal, dope and plastic, be characterized by excellent formability, heat insulation, weatherability, impact resistant, high intensity. For it’s excellent character and decorative effect, aluminium plastic plates be widely used on the great building, symbol structure and also the high-class abiding place. In Europe, it’s already the best choice for decorating building.

Q:Aluminum foil and aluminum foil is not the same
The first really tin foil made of tin foil paper but because is hard, and has a tin taste retained in the food defect, which later decreased after the price of aluminum foil, foil instead of in their daily lives. However, because of the influence of aluminum on the brain, the surface of the existing aluminum foil is coated with aluminum to avoid the release of the metal.
Q:mass of aluminum chloride that can be formed?
2 Al + 3Cl2 -- 2AlCl3 29 grams of Aluminium , 34 grams of Chlorine Atomic weight of Aluminium = 27 Atomic weight of Chlorine = 35.5 Therefore 29 / 27 (= 1.074) gram moles of aluminium atoms are available to react with 34 / 35.5 (= 0.958) gram moles of chlorine atoms BUT 3 times more chlorine atoms are required for this reaction than aluminium atoms therefore, only 0.958 / 3 (= 0.319) gram moles of aluminium can be consumed by the reaction to produce 0.319 gram moles of Aluminium chloride. The molecular weight of Aluminium chloride = 27 + (3 x 35.5) = 133.5 Therefore the maximum mass of Aluminium chloride that can be formed = 133.5 x 0.319 = 42.6 grams of Aluminium chloride
Q:What are the advantages of aluminum foil?
Aluminum foil material is soft metal film, the main advantages of which are as follows: 1.It is moisture-proof, air sealing, light shading, wear resistant, fragnance-holding, non-toxic and tasteless; 2.It has a silvery luster and is easy to print all kinds of beautiful patterns of all colors; 3. After aluminum foil composited with plastic and paper, it integrates shielding of the aluminum foil, strength of paper and thermal insulation of plastic, and further improves the shielding function of aluminum foil tape as packing material from moisture, air, ultroviolet rays and bacterial, which has greatly expanded the application market of aluminum foil.
Q:Aluminum foil foil uses what are the benefits?
Most of the foil side light, the other side of the aluminum foil with matte finish. Food can double wrapped food, are often recommended to light bread, enhance the heat conduction effect.
Q:aluminum for electrolysis?
You will rapidly form aluminium oxide, which will coat the positive electrode. After a while, this will diminish the current, so the efficiency of the electrolysis will be greatly reduced. The electrolysis itself is fairly safe (it is how anodised aluminium is made). But you'd be better off with a less reactive metal as your electrode, or one which does not form a protective oxide layer (or at least, not as easily).
Q:What's the highest temperature resistance of the aluminum foil ?
Aluminum foil is directly pressed by aluminum. Melting point: 660.37, fire point: 550℃. I’m not sure whether it can be installed, but since it is exhaust duct, the temperature may not be too high. It will not be much higher than 100℃ anyway as the boiling point of water is just 100℃.
Q:Would aluminum nails rust????
Aluminum Nails
Q:How about rubber & plastic aluminum foil thermal insulation board?
Featured by softness, flexibility, resistance to low/high temperature, fire resistance, waterproofness, low heat conductivity coefficient, shock absorption, sound-absorbing and other excellent properties, rubber & plastic aluminum foil thermal insulation board is widely used in cold and hot pipes and containers in central air conditioning, construction, chemical industry, textile, metallurgy, communication, vehicles, electrical appliances and other industries to reduce cold loss and heat loss.
Q:Is there any way to prevent corrosion oxide coated aluminum coil?
3. Strengthen the management of rolling oil, its water content control in 0.04% or less. 4. The color coated aluminum coil packaging should be sealed packaging, and each volume should be placed in an appropriate amount of desiccant.
Q:Need a good aluminum bodied RC helicopter?
aluminum okorder.com... if someone else finds another chopper, don't blame me, i'm human.
