ALPLAN 6082

Alplan 6082

Precision plates in ALPLAN® 6082 are milled on both sides and have a very low level of residual stress, thus avoiding excessive deformation during machining. Thanks to its very good dimensional stability and the elimination of surface milling operations, ALPLAN® 6082 plates enable to realize significant cost and time savings in machining, when compared to normal rolled plates.

PROCESSING METHODS

Weldability

  • TIG / MIG: excellent
    filler metal AA 4043 - AA 5356
  • Resistance: excellent

Anodizing

  • Technical: excellent
  • Decorative: excellent

Machinability: excellent

Corrosion behaviour:

  • Excellent in inland atmosphere
  • Good in marine atmosphere

AVAILABILITY
