Metals Presentation by Patricia Garrido

  1. 1. Metals Patricia Garrido Jiménez 1ºC I.E.S. Isaac Albéniz
  2. 2. Metals - Ferrous metals Ferrous metals are metals that contain iron. - Non-Ferrous metals Non-Ferrous metals are metals that don't contain iron.
  3. 3. Ferrous metals <ul><li>Wrought iron </li></ul><ul><li>Mild Steel </li></ul><ul><li>Carbon Steel </li></ul><ul><li>Cast iron </li></ul><ul><li>Stainless steel </li></ul>
  4. 4. Wrought iron <ul><li>Wrought iron is almost 100% iron. It is fibrous, tough and ductile. It is used in gates and railings but it is not very used today. </li></ul>
  5. 5. Mild Steel <ul><li>It is made up of a few carbon and iron. It's tough, it gets rusty easily. It has high tensile strength. It's most common used in school workshops and in engineering. It is used in nuts, bolts, screws and car bodies too. </li></ul>
  6. 6. Carbon Steel <ul><li>It has more carbon than mild steel and iron. It's tough and very hard. It is used in cutting tools such as drills and hammers. </li></ul>
  7. 7. Cast iron <ul><li>It has a lot of carbon (4%). It is strong but brittle, compressive strength very high. It is used in vices and kitchen pots. </li></ul>
  8. 8. Stainless steel <ul><li>It is made up of iron, nickel and chromium. It is hard and tough and it is resistant to rust and stains. It is used in cutlery, medical instruments, sinks, and kitchen utensils such as pots and pans. </li></ul>
  9. 9. Non-Ferrous metals <ul><li>Aluminium </li></ul><ul><li>Copper </li></ul><ul><li>Brass </li></ul><ul><li>Bronze </li></ul><ul><li>Silver </li></ul><ul><li>Lead </li></ul>
  10. 10. Aluminium <ul><li>It is light grey. It's a pure metal. It's ductile, soft, malleable, very light, it has good corrosion properties and it is a good conductor of heat and electricity. It is used in window frames, aircraft, kitchen ware, ladders and drink cans. </li></ul>
  11. 11. Copper <ul><li>It is reddish brown. It is a pure metal too. It's ductile, malleable, it conducts electricity and heat, it doesn't get rusty and it is easily bent. It is used in electrical wiring, tubing, kettles, bowls and pipes. </li></ul>
  12. 12. Brass <ul><li>It is yellow and it is an alloy of copper and zinc. It is hard, conducts electricity and it doesn't get rusty. It is used in ornaments and door handles. </li></ul>
  13. 13. Bronze <ul><li>It is yellow-red. It is an alloy of copper and tin. It is hard, it conducts electricity and it has good corrosion properties. It is used in coins, springs and turbines. </li></ul>
  14. 14. Silver <ul><li>It is whitish grey. It is made up of mainly silver but alloyed with copper to give sterling silver. It is ductile, malleable, solders and it is resistant to corrosion. It is used in jewellery and ornaments. </li></ul>
  15. 15. Lead <ul><li>It is bluish grey and a pure metal. It is soft and weak, it is heavy, ductile and it loses its shape under pressure. It is used in solders, pipes, car batteries and roofing. . </li></ul>
