Aluminium Introduction: The element Aluminium has a symbol of Al and has an atomic number of 13. It is a very light, soft and useful metal used for many things such as cans, foil and kitchen utensils. It is a ductile metal, a good conductor of heat and electricity, does not corrode and is a solid at room temperature. It was discovered in 1825 by Hans Christian Oersted in Denmark. Aluminium is one of the most used metals in the world as well as one of the most commonly found metals in the Earth’s
Physically and chemically Aluminium is a metal much like others such as; steel, copper and titanium. I can occur as a solid, a liquid or a gas and the state at which aluminium occurs depends on its condition, temperature and pressure. Aluminium is a very light weight metal at 2.7 grams per 〖cm〗^3, which is approximately one third the weight of steel. (HIGGINS, 1972) It naturally forms a protective oxide coating which protects it from corrosion; this oxide coating is thin but very dense and can be

Aluminium is a chemical element which is a metal, it is lustrous, ductile and non magnetic. Aluminium is also the third most abundant element on earth and the most abundant element
of aluminium propose it the best and ideal aspirant for replacing the heavy materials such as copper and steel in car and other luxury vehicles for full filling the requirement of automobile industries of weight reduction. In this essay we will discuss the recent development in application of aluminum alloy in casting, metal forming and extrusion process for automobile industries. We will consider two examples also where we will see that how automobile industries started to apply aluminium for
properties, why aluminium – the most common metallic element on our planet – was not extracted and used until the 19th century whereas gold, a much rarer element was one of the first metals used. (10 marks) Gold was discovered around 6000 BC; it was first discovered in its Natural state un-combined. Gold can be found in the earth’s crust in two different types of deposits: Lode deposits which are deposits in solid rock and placer deposits which are found in stream beds. Aluminium is the 3rd most
Aluminium The Consumer throws aluminium cans and foil into a recycle bin. The Aluminium is then collected and taken to a treatment plant. In the treatment plant the aluminium is sorted and cleaned ready for reprocessing. Aluminium is mainly used for cans, foil, kitchen utensils, window frames, Beer kegs and Aeroplane parts. POSITIVES: Since it takes more energy to dig up and produce Aluminiun than any other metal, recycling not only avoids resources to be extracted from Earth, it also saves energy

experiment, the unknown metals must be identified. The two metals are labeled as unknown metal A and B. The procedure informed the audience that one metal is Tin and the other is Aluminium. Knowing the physical properties of a metal, it came to a hypothesis that unknown metal A was Tin and unknown metal B was Aluminium. The reason to the hypothesis is unknown metal B had a shiny luster to it and had the same color as aluminum foil used for food. Therefore, unknown metal B is aluminum making unknown
Aluminium is present in the earth's crust in huge amount, mainly in the form of insoluble aluminium silicates. It is scarce in the human body which contain only 30-50 mg of that metal. This is due to the insolubility of aluminium, the presence of a barrier in the gastro-intestinal tract to soluble forms of aluminium, and the ability of the kidneys to excrete aluminium effectively in healthy people. Aluminium is present in food occurs in additives, tea which is rich in aluminium, and drinking water
squeezing a block of material such as Aluminium, forcing it through a die. The die has a job of reducing it’s diameter and increasing it’s length. This method results in a constant cross-sectional cut and a desired shape. The process of extrusion is mainly used in situations where the material can’t be hammered or bended due to their specific properties such as being too soft or too brittle. The common materials that can be extruded include metals such as Aluminium, Copper, Lead and steel, plastics

An ore is a mixture in the form of a rock that is mined. For example, bauxite is an ore that contains a high percentage of pure aluminium. That pure aluminium is then extracted, refined, and crafted in to many everyday items such as cars, foil, and ladders. Chemists are continuously researching an innovative

decided to sell two thirds of Rio Tinto based in Spain so that they can pump money into new developments in other countries. Extensive bauxite deposit was discovered at wepra far north Queensland Australia, that discovery led to Rio Tinto’s entry into aluminium and formation of Comalco limited that was in the year 1956. Six years later Conzinc Rio Tinto Australia was formed, in the year 1966 the first exports to Japan, in Western Australia Rio Tinto launched it’s iron ore operations with the launch of Hamersley

ALUMINIUM ALLOYS The alloys in which alluminium is a major components is called as alluminium alloys.alluminium alloys contains manganese, copper tin and lead are other major components.these alloys are usually used in air craft industries where light metals are employed to make aircraft bodies.alluminium alloys devalope an white coating due to the formation of alluninium oxide layer. In a moisture containing atmosphere, corrosion will happen when these alloys are kept with some other metals with
attachments and better engines. This is all in the aid of giving more time and quicker action in the increasingly hectic lifestyles of today. The basic trimmer works by the engine driving a multi-bearing supported hardened steel shaft housed in an aluminium tube through a centrifugal clutch this shaft is connected to a “head” that holds a nylon line that spun at high revolutions per minute (RPM). This nylon line then cuts the grass by hitting the blades of grass at high speed, this cause the grass to
adding carbon, the steel becomes harder and stronger and is more corrosion resistant than iron. Steel is malleable, and thus is easily welded and shaped into the forms needed to create car bodies. The cost of steel is low compared to metals like aluminium, which can also be used for car bodies but is expensive. Steel is plentiful and cheap. These properties make steel a suitable material for car bodies. By alloying copper – with the addition of nickel, cupro-nickel alloys have improved strength and
