  1. 1. EN. BADWIN SHAH BIN ZAWAWI MEOR SYUKRI BIN MEOR ARIS (2012281884) MOHD ZARAHAN BIN ZAKARIA (2012237574) HANIS RIDZHA MINARWAN BIN AHMAD ZUKI (2012808042) SITI ZALIKHA BINTI MOHD JAMIL (2012831838) AKMA SUHAILA BINTI MD NOOR (2012823774) NURUL ATIQAH BINTI ZAINOL (2012625514) MOHAMAD ALIFF FADZUAN BIN AHMAD ZUKI (201285084) SITI NUR SAKINAH BINTI SAEDON (2012821744)
  2. 2. From Greek word: • Metallon = ‘ mine,quarry,metal’ Element,compound,alloy – good conductor Shiny,malleable and ductile METAL
  3. 3. Aluminium Antimony Bronze Cobalt Copper Gold Iron Lead TYPE OF METAL
  4. 4. Lithium Magnesium Mercury Nickel Platinum Silver Titanium Zinc
  5. 5. aluminium antimony bronze cobalt copper gold iron lead
  6. 6. lithium megnesium mercury nickel platinum silver titanium zinc
  7. 7. METALS : calcium : copper : lead : aluminium : zinc : lithium : potassium COMMON METAL AND NON-METAL
  8. 8. NON - METAL : sulphur : oxygen : chlorine : hydrogen : bromine : nitrogen : idelium
  9. 9. Metal -Strong -Malleable and ductile -High melting and boiling points -Good conductor of heat -Shiny when polish -React with oxygen to form basic oxides CHARACTERISTIC
  10. 10. Non-Metal -React with oxygen to form acidic oxides -Dull sound when hit with hammer -Low melting and boiling point -Poor condustors of electricity -Dull looking -Low density
  11. 11. Ferrous • From Latin word = ‘Contain iron’ • Use in large quantity • Include pure iron • Wrought iron • Alloy ( steel ) • Magnetic • Non-magnetic is stainless steels Non-ferrous • Non-magnetic • Cobalt and nickel are exceptions CATEGORIES OF METAL
  12. 12. Base Metal • zinc, • Reacting with an acid • Use to refer to a metal • Oxidizes or Corrodes relatively easily • React variably with • Dilute hydrochloric acid ( HCI ) to form Hydrogen • Example : iron,nickel,lead
  13. 13. Noble Metal • Resistance to corrosion or oxidation • Perceived rarity • Examples : • Gold • Platinium • Silver • Rhodium
  14. 14. Precious Metal • Rare melallic chemical element of high economic value • Less reactive • High important as currency • Is a Gold and Silver • Include platinium group metal: • Ruthenuim,Rhodium,Palladium,Osmium,Iridium.
  15. 15. Iron • Used for strength application • Wrought iron contain • less then 0.2% carbon • Cast iron between 2-4% carbon • Iron with a carbon content between 0.2-2% is classified as steel. Iron
  16. 16. Examples of Iron Cooking panTraditional equipments
  17. 17. Aluminium • Is a alloy • Easy to form • Readily available • Inexpensive • Recyclable Aluminium
  18. 18. Examples of Aluminium Laptop Drinking Can Laptop’sCover
  19. 19. Copper • Have a number of properties that make them useful • Include : • High electrical • Thermal conductivity • High ductility • Good corrosion resistance Copper
  20. 20. CopperCoil Copper Spring
  21. 21. Titanium • Alloy • Strength in higher temperature ( ~1000’ F ) application • When component weight is a concern Titanium
  22. 22. Titanium Alloy Titanium Rods
  23. 23. Nickel • Alloy • Use for higher temperature ( ~1500-2000’ F ). • When good corrosion resistance is required. Nickel
  24. 24. Coin NickelTitanium Alloy
  25. 25. METAL - Made into jewellery due to their hard and shiny appearance -Used to make pans due to good conductor of heat -Malleable,ductile and good conductor of electricity and used in electrical cables USES OF METAL AND NON-METAL
  26. 26. NON – METAL -Used as insulating material around wire cables since they do not conduct electricity -Used to make pans handles as they are poor of conductors of heat
