designations

  • GOST 4784-97: AMC
  • EN 573-3: EN AW-3003 и EN AW-Al Mn1Cu
  • Международная регистрация (Teal Sheats)Aluminum Association: 6005A
  • Unified Numbering System (UNS): A93003
  • ISO 209: 3003
  • DIN 1725-1 (отменен): AlMnCu и 3.0517

metallurgical properties

  • Обрабатывается методами прессования (экструзии), drawing, hot and cold rolling.
  • The main alloying element – manganese. Manganese, among other things, It provides good control of crystallization and grain growth.
  • Another alloying element – copper. Copper contributes to the mechanical properties.
  • Типичными состояниями материала являются: H1x, H2x, O, H112.
  • H112 condition is typical for extruded profiles. В этом случае оно обозначает: “pressed and subjected to tension straightening”.
