Kwaliteit EN AW-1050A
EN AW-1050A is een ongelegeerd aluminium met maximaal 0,5% verontreiniging. Het materiaal is niet thermisch hardbaar. Verhoging van de sterkte is alleen mogelijk door koudeformatie (versteviging, conditie Hxx), hetgeen gepaard gaat met een afname van de rek en dus van de vervormbaarheid, waarbij de conditie H2x iets betere vervormingseigenschappen heeft dan de conditie H1x.
De corrosieweerstand is onder "normale" omstandigheden uitstekend en kan eventueel nog verbeterd worden door producten technisch te anodiseren. In zachtgegloeide toestand (O) is dit materiaal uitstekend te vervormen (buigen, dieptrekken, forceren e.d.). Bij het lassen van EN AW-1050A in de koudverstevigde toestand moet in de warmtebeïnvloedbare zone rekening gehouden worden met een daling van de sterkte naar het niveau van de zachtgegloeide toestand.Toepassingen zijn o.a. opslagtanks, warmtewisselaars, verpakkingen, reflectoren e.d.
Lasbaarheid: goed
Lastoevoegmaterialen: 1050A, 4034
Warmtebehandelingen: warmvervormen 550 -330°C / zachtgloeien 320 -350°C
