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:Why does aluminum react this way?
Aluminum reacts like the elements in its group, the elements that are above and below it, such as Boron and Gallium. This is due to its valance electrons which you can find out through its electron configuration. It has 3 valance electrons, while the other elements you mentioned follow different rules due to their valance electrons. Ultimately, aluminum does not act like those because it is not in that family/group.
Q:Is it bad to burn aluminum foil?
No. The aluminum will usually not burn. At a temperature in excess of 1150 degrees, and being exposed to an open flame at the same time, will result in the aluminum burning. On a barbecue, you will only have a few hundred degrees. When aluminum burns, it will naturally produce aluminum dioxide, which is not toxic. You don't have anything to worry about. Aluminum only burns in fine powder form, or when it is melted (exceeding 1150F)
Q:Quick help Please..Why is aluminum such a useful metal in spite of the fact that it is very reactive?
It is light, much lighter than iron. It is easily formed using standard machine tools. Sheet aluminum can be even cut with wood cutting blades. It does not rust. Even though aluminum corrodes, it's oxide it a strong cohesive ceramic which adheres to the metal and does not flake off. Aluminum can be used without corrosion protective coatings and will stand up to the elements. Aluminum can be easily alloyed with other metals to achieve specific, desireable properties. It is strong for it's weight and pound for pound, can replace steel. Lastly - it is abudent and not expensive and easily smelted from the raw ore using electricity.
Q:iron rust but not aluminium? 10 points.?
Aluminum DOES rust..... It oxidizes just like iron does..... Leave a piece of aluminum outside for a few months.... It will get a nice white powder on it which of course is aluminum oxide
Q:What kind of paint would you like to paint on the aluminum plate?
Try to brush the high quality magnetization paint, the aluminum plate brush can be brushed, will not move, also won't fall lightly.
Q:What are the features of the poor aluminum profiles?
Low precision, bad feel, and so on, some inferior shape.You'd better go to the manufacturer you trust.
Q:What are the features of wood grain aluminum veneers?
1, exquisite appearance, grain pattern rich, realistic effect, clear texture.2, fire resistance: corrosion resistance, moisture resistance, hardness and strength are compared to wood floating method.3, rust prevention, anti damage, UV protection.4, long service life, can maintain 10-15 years without color, no deformation.5, strong plasticity, can be processed into a variety of complex shapes, the back of which can be filled with insulation, sound insulation, sound-absorbing and other materials, so that its function more rich.6, environmental protection, ecological environment protection, reduce waste of materials and resources.
Q:Top 10 ranking enterprises of aluminum profiles in China
I know one of the national top five hundred aluminum companies not in the aluminum industry ten strong, sure it is moisture ah, Seoul not lose ten of the aluminum industry
Q:Aluminum water bottles or stainless steel bottles?
Answer to all your questions is stainless steel. Stainless steel prevents it from rusting and getting more bacteria compared to aluminum. People usually use stainless steel mugs for coffee and I too use stainless steel products for drinks.
Q:What is aluminum foil tape?
Low temperature, the first thought is fridge and freezer, yes, low temperature aluminum foil tape fixed above refrigerators, freezers and other appliances metal pipe played a magical role, in addition, it also applies to all joints paste composite aluminum foil, as well as cotton insulation panels and ducts airtight vapor and the like.
