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.

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:How to remove the adhesive sticker in aluminum foil bag?
Wipe it with alcohol or liquor with higher concentration.
Q:What causes the pinholes of the aluminum foil?
Due to improved foil rolling conditions, particularly dust and rolling oil effectively filter and convenient roll changing system settings, the number of aluminum foil pinhole increasingly dependent on the metallurgical quality of the raw material and processing defects due to pinholes often defects in materials shedding, it is difficult to find the correspondence between the original defects.
Q:Aluminum corrosion resistance is mainly reflected in what areas?
The second is resistant to salt spray corrosion test conditions generally in the 35 oC, 3% salt spray environment requires 500 hours can not have spots of corrosion. Salt spray corrosion resistance is directly related to the heat transfer sheet length of life. In coastal areas, due to the high salt content in the air, so the heat transfer sheet of salt spray corrosion resistance have high requirements;
Q:What's the application field of aluminum foil?
Aluminum foil can be used to roast fish and meet, pack dim sum and snacks, reserve leftovers, decorate items and clean.
Q:How to judge whether the aluminum foil bags up to standard?
2, adhesive aspect - special adhesive is solvent-containing substance, which under certain conditions applied to the dark side of the original aluminum foil, and bake drying after forming an adhesive layer on the heat seal strength of the product plays decisive role.
Q:Why aluminum foil should be used in capacitor material of distributors?
The normal metal capacitor, especially CBB21/,DV/, impulse current of its turn-off voltage is very high. The capacitor material of distributors, if the distributors of ignitor can't bear such high impulse current. Using CBB28 or CBB8,in which the capacitor can bear a higher impulse current.The ratio of DT is higher.
Q:What are the classification of aluminum foil compound insulation material?
There are a variety of insulation materials with wide application. The commonly used ones include glass cotton products, heat insulation blankets and heat-insulated foam glass, polyurethane foam glass, etc. The glass cotton products are used in air conditioning insulation, duct insulation, polyurethane foams, extruded polystyrene board, molding of polystyrene, Bakelite resin, mineral fiber products, polyphenyl granule size, compound wood, soft wood, etc. Polyurethane foam is currently a kind of insulation material with minimum coefficient of heat conductivity of 0.018~0.024W/(m·k)in building insulation.
Q:What's the difference between PTP aluminum foil and conventional soft packing used aluminum foil?
PTP aluminum foil can't resist high temperature while conventional soft packing used aluminum foil does.
Q:Why are the aluminum coils sticky after annealing?
There is oil or the annealing time is too long!
Q:How to remove the oxide layer in the aluminum foil with a chemical process?
Aluminum is easy to react with oxygen in the air, so even if you remove the aluminium oxide in the surface, it will soon be oxidized again.
