7. Complete the map with the correct words.

FERROUS AND NON-FERROUS METALS

Ferrous metals:
Predominant element: 1.
• iron: used in 2. for malleability, ductility, magnetic property, heat 3.
• steel: alloy = iron + other elements + 4. (characteristics change according to 5. of carbon)
• 6. iron: alloy = iron + carbon, hard and 7.
• wrought iron: almost 8. iron + slag, excellent resistance to 9. and oxidation

Non-ferrous metals:
Characterized by the fact that they are iron-free. The most commonly used are:
• aluminium: light, 10. resistant, non-magnetic, good 11. and electrical conductor
• 12. : excellent electrical conductivity but 13.
• titanium: light, strong, high corrosion resistance, high 14. point
