CERTAL SPC®

High-strength Rolled Plate CERTAL SPC® 

Alloy EN AW 7122 [AlZn5Mg3Cu], typ specjalny
Type of Alloy hartowany
Temper T651/ T652, odprężony przez rozciąganie (grubość 150 – 170mm) / stan spęczony (grubość 180-200mm)
Surface struktura po walcowaniu lub szczotkowana

The high-strength rolled plate CERTAL SPC® is made of alloy AA 7122, a modified version of alloy EN AW 7022 (AlZn5Mg3Cu) and is available at up to 300 mm in thickness. The 150 to 180 mm thicknesses are produced both in stretched (T651) or compressed (T652) versions, from thicknesses >180 mm, always in T652. Compared with other high-strength rolled plates, CERTAL SPC® has a significantly lower strength and hardness decrease from plate edge to centre and is therefore much more dimensionally stable than, for example, rolled plates made of EN AW 7075.

Special features

  • Very high strength
  • Very low strength decrease over the cross section
  • Excellent polishing properties
  • Very good machinability
  • Good dimensional stability

Końcówka Expert

Jeśli zachodzi potrzeba gięcia lub krawędziowania płyt walcowanych, wówczas aby uniknąć pękania materiału lub powstawania włoskowatych pęknięć, krawędź zginania powinna w zasadzie przebiegać w poprzek kierunku walcowania. Nigdy nie należy oznaczać (trasować) krawędzi gięcia ostrymi przedmiotami, takimi jak rysik traserski. Szczególnie dobrze gięciu poddają się płyty walcowane EN AW 5754 i 5083, płyty aluminiowe z odlewu, ze względu na mikrostrukturę nie nadają się do gięcia i krawędziowania
