Corrosion Resistance |
|---|
Corrosion resistance similar to series 1xxx, better against
chlorides and alkaline solutions. Good atmospheric corrosion
resistance and against freshwater, seawater, organic acids,
aldehydes. All aluminium alloys are subjected to pitting corrosion in presence of chlorides. |
