- 1engeneering materlials can be divided into:-metals: iron(FE); copper (CU)
-non-metals: carbon (C); silicon (Si) - 2Metals can be divided into:-ferrous metals: those that contain iron
-non-ferrous metals: those that do not contain iron: copper - 3Elements Definition:pure materials in their most basic form. They cannot be broken down into different constituents
- 4Elements exampleiron
carbon
aluminium - 5Compounds definitionconsist of two or more elements that are chemically bound- that is, combined by a chemical reaction
- 6compounds examplewater (which is a compound of hydrogen and oxygen)
- 7mixtures definitionconsist of two or more elements or compounds which are mixed togehter, but which are not chemically bound.
e.g. alloys - 8alloy definitionmetals which have other metals and/or non-metals mexed with them.
alloys are much more widely used than pure metals - 9alloy examplesteel: an iron-carbon alloy
- 10alloying metalsmetals which are added to alloys, in small quantities relative to the main metal
- 11alloying metall examplechronium (Cr)
manganese (Mn)
tungsten (W) - 12aluminium alloysused in construction of aeroplanes, automobiles, bicycles and buildings. pure aluminium parts corrode too easily, so they are unsuitable fore use in aeroplanes and buildings
- 13why are alloys so important?alloys combine the most useful properties of different metals to form an alloy that is superior and specific to what it is needed for than just a pure metal, thus you may need less pure metal with an alloy
- 14verstärken; aussteifenreinforce
reinforced concrete
reinforcing
reinforcement - 15composite definitionMade up of several parts or elements
