Aluminium Alloy 3003 H14 Data Sheet

Aluminium Alloy 3003 is a medium strength alloy with very good resistance to atmospheric corrosion and very good weldability as well as good cold formability. It has better mechanical properties, especially at elevated temperatures than the 1000 series alloys.

Applications for Aluminium Alloy 3003

  • Building industry
  • Roofing and sidings
  • Acoustic ceilings
  • Insulation panels
  • Corrugated sheets
  • Storage tanks
  • Motor vehicle radiators
