Picture b.m presentation

  1. 1. FERROUS METAL  Contain large % of iron (Fe)  Subject to attack rust  Wrought iron and cast iron are less affected  Example : IRON CAST IRON WROUGHT IRON STEEL
  2. 2.  With Carbon : - Increase metal strength and hardness - Reduce ductility  Without Carbon : - Soft - Malleable - Silver-white look - Will rust and corrode when expose to acids
  3. 3.  Hard  Corrosion-resistant  Strong and cheap  Malleable when carbon remove  Application : stove, stairs, pipe, decorative pieces
  4. 4.  Tough and ductile  Relatively soft  Purest form of iron, contain about 0.02% carbon  Corrosion of resistance  Applicable : - Gates - Railings - Fences
  5. 5.  Metals not made of iron but made of other metallic elements  More expensive than iron or steel  No contain iron, therefore no rust  Example : NON-FERROUS METALS Aluminum Brass Bronze Copper Lead Magnesium Tin Zinc
  6. 6.  Silver-white metallic  Soft & flexible  Ductile  Good conductivity of heat and electricity  High resistance to corrosion  Applications : - Section for window and door frames - Door and window furniture
  7. 7.  Malleable and ductile  Corrosion-resistant  High thermal and electricity conductivity  Application : - Pipes - Roofing - Gutters
  8. 8.  Soft but heavy  Poor electrical conductor  Corrosion-resistant  Application : -
  9. 9.  An alloy mixture of copper & zinc  Strength and hardness depends on zinc content  Yellow in color  Improve strength and corrosion-resistant  Application : - Soft brass for door & window - Furniture - Hard brass for plumbing connections
  10. 10.  Pinkish  Mixture of copper & tin  Greater % of tin, more stronger  Applications : -
