Resistance Aluminium naturally generates a protective oxide coating and is highly corrosion resistant. Different types of surface treatment such as anodizing‚ painting etc. can further improve this property Electrical and Thermal Conductivity Aluminium is an excellent heat and electricity. This has made aluminum the most commonly used material in major power transmission lines. Reflectivity Aluminium is a good reflector of visible light‚ which

Energy: # Bayer process – when bauxite is refined to create alumina it requires 15 000 MJ of energy per tonne. # Electrolytic reduction - when alumina is refined to create aluminium it request 100 000 amps per tonne. # Refineries and smelting factories they need their own power plant because of the amount

Introduction to Automotive Systems Technology Assignment No.1 Research and discuss the use of steel as a material for the construction of vehicle bodywork and also the reasons why Glass fibre or Aluminium may be used. Benjamin Lichtenberg DT007/1 Submission Date: Monday 6th November 2006 After wood became obsolete as a building material for automotive chassis and bodies‚ steel became the most popular material for the Automotive Industry to use for vehicle bodies. In 1922 the American

and larger and greater specifications are desired. The initial step of metallurgy should be to create aluminium oxide. In alumina oxide production with sintering process‚ we need to first create the raw materials compounded by bauxite‚ limestone and alkali into clinker. The sintering process is completed within the vertical roller mill whose inner temperature is 1300℃. The final phase of aluminium oxide manufacturing is to roast aluminum hydroxide into alumina oxide. The inner temperature is about

METAL METHOD OF EXTRACTION Potassium Sodium Lithium Calcium Magnesium Aluminium K Na Li Ca Mg Al These metals are too reactive for ordinary chemical reducing agents like carbon to be used. They are obtained by electrolysing their molten compounds. For aluminium‚ aluminium oxide (from the ore Bauxite) is used For Group 1 and 2 metals‚ the metal chlorides are usually used. Electrolysis is a very expensive process because

known as an ore. The method used to extract metals from ores depends on the reactivity of that metal. Some unreactive metals can even be found in the native state‚ like gold. On the other hand‚ most metals are too reactive to exist on their own like aluminium‚ which has to be extracted using a method called electrolysis. And some moderately reactive metals that are in the middle of the reactivity series can be extracted using reduction of oxides like iron. Gold is not found in a mixture or
