Anticorodal Bar
EN AW 6082

An alloy with average mechanical properties that's primarily used in the mechanical engineering and automated machinery construction industries.

Thanks to its combination of good corrosion resistance, excellent weldability, and suitability for anodic oxidation, this alloy represents an ideal compromise for any application.

technical characteristics

Weldability

  • TIG/MIG: optimal
  • Filler wire: AA 4043 / AA 5356
