metals


                                                                     METALS

-A solid material which is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity .

-Ferrous: 
  • Vehicle scrap metal
  • Demolition Site scrap metal
  • Metal offcuts from manufacturing industries
-Non-ferrous:
  • Aluminium & Aluminium Alloys
  • Copper
  • Brass
Metals:
Strong
Malleable and ductile
React with oxygen to form basic oxides
Sonorous
High melting and boiling points
Good conductors of electricity
Good conductors of heat
Mainly solids at room temp. Exception mercury - liquid at room temp.
Shiny when polished
When they form ions, the ions are positive
High densit

-Alloys:

     ·Steel, a combination of iron (metal) and carbon (non-metal)
     ·Bronze, a combination of cooper (metal) and tin (metal) 
     ·Brass, a mixture of copper (metal) and zinc (metal)

-New materials:

superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation
