METALS

1. Ferrous metals mainly contain IRON

   • cast iron
     • 2% iron and 6,67% carbon
       • Used to:
         • tools
         • street lights
         • manhole cover
         • machine structures
   • steel
     • 0,1 or 0.2 of carbon
       • Iron + carbon + a few of other of other material
         • Resistent, inexpesive, hard
   • iron
     • less than 0,1% of carbon
       • soft, ductile, mallebe
         • electronic nad medicine uses

2. Non-ferrous metals mainly dont contain IRON

   • cooper
     • bright red-coulored
       • used to:
         • ornaments
         • coins
         • weapons
         • gas pipes
   • tin
     • silver-coulored and shiny
       • ductile and malleable
         • easy melt
           • non toxic
   • aluminium
     • white-colored. shiny and cheap
       • very light
         • resistent to corrosion
           • good conduction
             • non-toxic
   • zinc
     • malleable
       • good conductor
         • highly resistent
