MAIN CHARACTERISTICS
- High strength aluminum plates
- Very good dimensional stability
- Low internal stress
- Good weldability
- Good corrosion resistance
AW 7021
This aluminium is produced from AW 7021 "Cast" obtained by casting process. It fills a gap between medium and high resistance alloys, the latter being in many cases undervalued. It is characterized by a very low microporous homogeneous structure, excellent machinability and high resistance.
