ALUMINIUM


ALIMINIUM-


-In terms of weight it makes up 8% of the earths surface.

-Aluminium is known for the metal's low density and for its ability to resist rusting/corrosion.     

-Compared to steel aluminium is about 1/3 the hardness of the more commonly used steel.               

-Aluminium is a soft, durable and lightweight metal but when bonded with other metals to create aloys its tensile strength/hardness is elevated .


-Most of the uses that aluminium has, are when it is bondod to make an alloy rather than as a pure metal, this is because pure aluminium simply isn't strong enough for usage in aeroplanes, cars, trains and buildings.

  1. Hi Greg looking at your presentation you might what to change the format, its difficult to read

  2. ALLOYS

    Aluminium alloys
    -Some of the other metals which are bonded with aluminium to create these different alloys are copper, magnesium, manganese, silicone and zinc

  3. These alloys are used for boat building and shipbuilding because of the non corrosive qualitys they have.

    5052 aluminium
    5059 aluminium
    5083 aluminium
    5086 aluminium
    6061 aluminium
    6063 aluminium

    These aluminum-magnesium alloys retain good weld strength without after-weld heat treatment, and they can be made with normal shipyard techniques and equipment. The aluminum-magnesium-zinc alloys are also also receiving attention in the marine industry.

  4. So overall when aluminium is in its original state its soft and maluble, but when its bonded with - zinc, copper, magnesium, manganese and silicone it creates alloys which are workable, lightweight and recyclable
