Aluminium is the most abundant metal in the world; however it can be quite expensive due to the extraction method‚ electrolysis. Aluminium ore is called bauxite‚ it is then purified into a white powder (aluminium oxide) then the aluminium can be extracted. To turn it into aluminium they heat the powder till it’s molten so electricity can pass through it. Its melting point is over 2‚000 Celsius‚ so it would therefore be quite expensive. One way of cutting costs is by dissolving it in molten cryolite

Aluminium The history of Aluminium use Aluminium is now one of the most widely used metals‚ but one of the hardest to refine due to it’s reactivity with other elements. Even as late as the turn of the century‚ Aluminium was considered very valuable and in turn expensive‚ even more expensive than gold. In some cultures‚ when a function was held (for example‚ a party) by wealthy people‚ only the most honored guests would be given Aluminium cutlery‚ the others had to make do with gold or silver cutlery

Pure aluminium is a relatively soft‚ silvery white metal. When exposed to air‚ a thin coating of Aluminium oxide gives it a dull lustre. It is three times less dense than water‚ and has great strength when alloyed‚ it doesnt rust and has high electrical conductivity‚ and Aluminium is also ductile‚ making it a very useful metal. Aluminium readily makes alloys with copper‚ zinc‚ magnesium‚ manganese and silicon. Aluminium foil is 92-99% pure aluminium. Other uses of aluminium alloys include computers

Shisir 2 ABSTRACT Aluminium and their alloys are widely used as construction materials from house hold appliances to air-craft parts. The commercially pure aluminium has merely low corrosion resistance and hardness compare to aluminium alloy. In this study an attempt has been made to study the influence of heat treatment on the properties of commercially pure aluminium. The investigation was

ABSTRACT The primary aim of this paper is to study the Microstructual influence on fracture resistance in 7000 seriers aluminium alloys. Fracture toughness is an indication of the resistance of a material to physical separation by a process of unstable macrocrack propagation. The microstructural features such as coarse particles of intermetallic (IM) phases‚ dispersoids‚ inter- and intragranular precipitates‚ precipitate-free zones ‚ grain size and orientation are known to exert significant effects
