- Aluminium (or aluminum; see different endings) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal.Aluminium is the third most abundant element (after oxygen and silicon) in the Earth 's crust, and the most abundant metal there. Aluminium is used to make food containers, because of its resistance to corrosion. 2  Aluminium with magnesium [alloy] is used to make body of aircraft. 3  Aluminium with other metals, used to make railway tracks. 4  Aluminium is used to make cooking utensils, because it is resistant to corrosion, and light-weight.

Everyday Items Made from Aluminum Combined with other minerals, aluminum is found in the kitchen of almost every home. All the cans that contain your sodas and juices are made of aluminum, so are a few of the TV trays used for frozen meals. You may use aluminum to cook your food, since there are pots and pans made from aluminum. In addition, do not forget the easiest and most used thing in your kitchen that is made of aluminum, foil. Foil used to be made out of tin, but tin leaves a metal taste on food, so aluminum replaced tin as the household foil in 1910.

- Alumina is used for the production of aluminium metal, through the Hall–Héroult electrochemical smelting process. It is also used in applications such as industrial and medical ceramics, sandpapers, pigments, cosmetics and pharmaceuticals. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production. The process stages are:

Extracting Aluminum But, extracting aluminum from alumina was very difficult, and for most of the 1800s, aluminum was rare and expensive.It was so valuable that kings and queens had fine tea sets and ornamental objects made of aluminum.It doesn’t rust and can be shaped and cast.his aluminum is not found as pure aluminum metal but is combined with other elements in the form of aluminum compounds. Today, aluminum is used for everything from airplane frames to soda cans and baseball bats.

Marine Applications of Aluminum Alloys: Part One Aluminum is used for boat trim and accessories, regardless of hull material. Anodized bright trim, either as extrusions or roll-formed sheet products, is widely used in boats of all types for rub rails, dash panels, and other parts. Small boats are fabricated from a wide range of aluminum sheet alloys, mainly in the 5xxx and 6xxx series. These have an optimum combination of strength, cost, ease of fabrication, and corrosion resistance. Generally, 5052-H32, 5052-H34, or 6061-T6 is used for small hulls that need no stretch forming.

- Uses of Tin. Tin is mostly commonly used in alloys, and in tin plate which is a thin sheet of steel with a protective coating of tin. Tin plate is used for food cans because it is not reactive to the acids present in food.

- Buildings made with aluminum are virtually maintenance free due to the strength of aluminum's corrosion resistance. Due to this and its light weight it is used in cladding, windows, skylights, gutters, door frames, and roofing.eight is also important in aluminum's electrical uses, where it's low density 2 makes it the first choice for long distance powerlines despite having just 63% of the electrical conductivity of (much denser) copper. In fact 1 kg of aluminum conducts almost twice as much electricity as 1 Kg of copper.

How and why alloying elements are added to aluminum Some of the common applications of the 7xxx series alloys are aerospace, armored vehicles, baseball bats and bicycle frames. Iron (Fe) – Iron is the most common impurity found in aluminum and is intentionally added to some pure (1xxx series) alloys to provide a slight increase in strength.

Alumina The chief uses for alumina are for the production of aluminum metal and for abrasives, but it is also used for ceramics, refractories, pigments, catalyst carriers, and in chemicals. Aluminum oxide crystals are normally hexagonal, and are minute in size. For abrasives, the grain sizes are usually from 100 to 600 mesh.

Why Iâm Concerned About the Dangers of Aluminum Aluminum is the most widely distributed metal on the planet and it’s used in the production of many every-day products. Cookware is made from aluminum, soda cans are aluminum, and aluminum foil is found in most kitchens. Aluminum is also in antacids, aspirin, vaccines, and even flour. This overwhelming infestation of aluminum means that your risk of exposure is through the roof, which is also made of aluminum. Unlike vitamins, minerals, and trace elements, the body does not need aluminum. And aluminum is no innocent or benign participant. Aluminum accumulates in the kidneys, brain, lungs, liver and thyroid where it competes with calcium for absorption and can affect skeletal mineralization. In infants, this can slow growth.

Castings The process of casting aluminum. Casting is the original and most widely used method of forming aluminum into products. Technical advances have been made, but the principle remains the same: Molten aluminum is poured into a mold to duplicate a desired pattern. The three most important methods are die casting, permanent mold casting and sand casting.

Aluminum Plate Properties and Applications Aluminum Plate can be used in various applications due to unbeatable strength to weight ratio compared to other metals. Weighing in at 1/3 as much as Iron, steel, copper or brass, aluminum is the most abundant metal element in Earth's crust and makes up about 8% by weight. Aluminum is corrosion resistant and and virtually maintenance free.

Aluminum Oxide Aluminum oxide, also called alumina, is used in engineering ceramics. It’s hard and wear-resistant, resists attacks by both acid and alkali substances, has high strength and stiffness, and has good thermal conductivity, which makes it valuable in manufacturing a variety of different ceramic products.etallic aluminum is reactive with oxygen, which could cause corrosion to build up. However, when aluminum bonds with oxygen to form aluminum oxide, it creates a thin coating that protects it from oxidation. This keeps the aluminum from corroding and losing strength.
