ferrous metals

• What is the main reason companies package products in metal containers for special occasions?

  To provide added security and visual appeal
• What are some benefits of using metals in commercial packaging?

  Added security and proof of tampering
• How can metal containers be customized for visual appeal?

  They can be embossed or debossed
• What is the definition of hardness in materials?

  Hardness is how well materials resist deformation and wear
• What does ductility refer to in materials?

  Ductility is the ability to deform without breaking
• How does temperature affect ductility?

  Ductility increases in metals with heat
• What is malleability in materials?

  Malleability is the ability to be permanently deformed without fracture
• How does temperature affect malleability?

  Malleability increases with temperature
• What are the categories of metals?

  • Ferrous Metals
  • Non-Ferrous Metals
  • Alloys
• What are some examples of ferrous metals?

  • Cast Iron
  • Steels
  • Mild Steel
  • Ferrous Alloys
• What are some examples of non-ferrous metals?

  • Aluminium

• What percentage of the Earth's crust is made up of metal ores?

  25%
• Which metal ore is the most common?

  Aluminium
• What is a key environmental concern regarding metal ores?

  They are non-renewable and unsustainable
• What are the characteristics of ferrous metals?

  • Contain iron
  • Corrode if unprotected
  • Attracted by a magnet
• How does the addition of carbon affect iron?

  It improves the hardness and toughness of the material
• What happens to the toughness of iron when carbon content increases?

  Toughness reduces, making cast iron brittle
• How can the properties of iron be changed?

  • By changing the amount of carbon added
  • This creates different types of steel
