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

The graduations are oversized by a proportionate amount‚ for example‚ when constructing a pattern for aluminium alloys‚ the pattern maker uses a contraction

He was back to living in his miniscule cupboard under the stairs and being treated like a servant from day to day. Dudley had made some new friends at Smeltings this year who ended up being even worse than his old friends. After a few weeks‚ Harry had had enough. He thought it was time someone taught the Dursley family a lesson‚ and with his new secret weapon‚ Harry was just the one to do it. It was the

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
