2.3 Aluminium Alloys Aluminium is the world’s greatest plentiful metal in addition to that it is the third most common element consist of 8% of the earth’s crust. Aluminium alloys are alloys where Aluminium (Al) is a prominent metal. The most broadly used metal next to steel is aluminium owed to its adaptability in nature. Even though aluminium compounds must been recycled from thousands of years, on the other hand aluminium metal was first produced around 170 years ago. In the 100 years, universal request for aluminium has developed to about 29 million tons each year. Aluminium is one and only the lightest engineering metals, consuming high strength to Weight ratio. Aluminium is being active in an ever-increasing amount of applications by …show more content…

Mutually further divided into two sorts i.e., heat-treatable and other one is non-heat-treatable. Approximately 85% of Aluminium is used as wrought products. Rolled plate, foils and extrusions are various instances for wrought products. But being owed to small melting point and commonly lesser tensile strengths than wrought alloys, Cast Aluminium alloys produces cost effective products. Al-Si is the supreme significant cast Aluminium alloy arrangement, where the high stages of silicon, i.e. 4% to 13% donated to provide good casting features. The light weight or corrosion opposition is compulsory in the engineering structures and elements, the Aluminium alloys are widely …show more content…

The numeral following the decimal point directs whether the alloy is a casting (.0) or ingot (.1 or .2). A capital letter prefix entitles alteration to a particular alloy. Example: Alloy - A356.1 the capital A (Axxx.x) specifies a variation of alloy 356.1 the number 3 (A3xx.x) specifies Silicon plus copper and/or magnesium series. The 56 (Ax56.1) recognizes the alloy within the 3xx.x series. The .1 (Axxx.1) specifies that it is a final shape of ingot. The composition, physical, mechanical properties of A356.1 Aluminium alloy are revealed in table 2.3, 2.4, 2.5 respectively. Table 2.3: A356.1 Aluminium alloy Composition.

    For example, what are the names of Fe2O3 and FeO. Iron oxide is not an adequate answer; it fails to distinguish between the two possible oxidation states of iron. Is it iron (II) or iron (III). To decide, you must know use the combination of the oxide's fixed oxidation state of 2- with iron's oxidation state required to total for a compound charge of zero. The compound iron(II) oxide, FeO, iron had the oxidation state of 2+ which balances the charge of the oxide ion which is 2-. For the compound iron(III) oxide, Fe2O3, the roman numeral placed after the name of the metal clearly states the charge of each iron atom as 3+. The older system of naming applies either the suffixes —ic for the ion of higher charge and —ous for the ion of lower charge; thus Fe3+ ion can be referred to as ferric and Fe2+ ion as ferrous.

    Aluminum is a lightweight, silvery metal. The atomic weight of aluminum is 26.9815; the element melts at 660° C (1220° F), boils at 2467° C (4473° F), and has a specific gravity of 2.7. Aluminum is a strongly electropositive metal and extremely reactive. In contact with air, aluminum rapidly becomes covered with a tough, transparent layer of aluminum oxide that resists further corrosive action. For this reason, materials made of aluminum do not tarnish or rust. The metal reduces many other metallic compounds to their base metals. For example, when thermite (a mixture of powdered iron oxide and aluminum) is heated, the aluminum rapidly removes the oxygen from the iron; the heat of the reaction is sufficient to melt the iron. This phenomenon is used in the thermite process for welding iron .

    Most components of bikes are either made out of steel or aluminium. Aluminium is commonly being used to replace components of steel bicycles as it is much lighter and retains nearly as much strength. Aluminium is more corrosive resistant and has a more aesthetically pleasing surface finish compared to steel. This is extremely important to bicycle design as a product that corrodes less and is lighter appeals to cyclists.

    Aluminum is one of a number of soft metals that scientists call "poor" metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure aluminum melts at 660.2ºC and boils at 2500ºC. Its density is 2.7 grams per cube centimeter. Aluminum is never found uncombined in nature. (Bowman, 391) Aluminum is a very useful metal that is light, easy to shape and can be strong. This makes aluminum one of the most used metals in the world, right behind iron and steel. (Geary, 185) In its pure state, aluminum is quite weak compared to the other metals. However, its strength can be greatly increased by adding small amounts of alloying elements, heat-treating, or cold working. Only a small percentage of aluminum is used in its pure form. It is made into such items as electrical conductors, jewelry, and decorative trim for alliances and cars. A combination of the three techniques has produced aluminum alloys that, pound for pound, are stronger than structural steel. Some common metals used in alloys for aluminum are copper, magnesium and zinc.(Walker, 31) The added elements give the aluminum strength and other properties. (Newmark, 41) Aluminum is one of the lightest metals. It weighs about 168.5 pounds per cubic foot, about a third as much as steel which weighs 487 pounds per cubic foot. (Neely, 214) As a result, aluminum has replaced steel for many uses. For example, some ...

    The metals are then taken to their own respective furnaces due to each one of these having different melting points and they are melted down. Afterwards the metals undergo a purification process known as the electrolysis process. This process will remove impurities in the metal to improve its overall quality. After the metals are melted and purified they are casted, typically into bars and ingots for steel and into sheet metal for aluminum. Afterwards, these ingots and sheets are then distributed to places that will make use of them for example a car factory that will use these metals for the manufacture of

  • Aluminum Recycling

    Aluminum is an element in the boron group with a symbol of Al, and an atomic number of 13. Aluminum is a very soft metal when pure but becomes strong and hard when alloyed, a malleable metal with a silvery gray color. Aluminum is a very reactive element so it is found in nature combined with other elements. Aluminum resists corrosion by the formation of a self-protecting oxide coating. Aluminum is the third most abundant element in the Earth’s crust, following oxygen and silicon. It makes up approximately 8% by weight of the Earth’s surface. Although this is evident, it is also apparent that aluminum is never found by itself in nature. All of the earth’s aluminum has combined with other elements to form compounds and in order to create new aluminum products; it has to be taken out of that specific compound. Aluminum does not rust like other elements, therefore it always remains strong and shiny, which means reused aluminum is almost identical to a brand new piece of metal. An electrochemical process creates aluminum. An electrochemical process is “the direct process end use in which electricity is used to cause a chemical transformation” ( E.I.A. Government). Major uses of electrochemical processes occur in the aluminum industry in which alumina is reduced to molten aluminum metal and oxygen, where than the aluminum can be used into making several different materials. Electrochemical processes, although very useful, can have serious environmental consequences. To help reduce the consequences that the production of aluminum creates, the idea of aluminum recycling comes into play.

    Metals possess many unique fundamental properties that make them an ideal material for use in a diverse range of applications. Many common place things know today are made from metals; bridges, utensils, vehicles of all modes of transport, contain some form of metal or metallic compound. Properties such as high tensile strength, high fracture toughness, malleability and availability are just some of the many advantages associated with metals. Metals, accompanied by their many compounds and alloys, similar properties, high and low corrosion levels, and affects, whether negative or positive, are a grand force to be reckoned with.
