comparison of alloys 6060, 6063 and AD31

See. table 1 and figure below. Alloy 606035 – internal company HYDRO c alloy narrowed intervals of chemical elements in the alloy 6060. This alloy is often used in the production of aluminum profiles for walling – window, doors, facades.

Metallurgical characteristics

  • Wrought
  • Thermally hardenable
  • Частичные аналоги: сплавы 6063 and AD31.
  • Compared with 6063 AD31 and abortion 6060 It has an excessive content of Si relative to the magnesium. The silicon content is about the same, а содержание магния значительно ниже: 0,35-0,6 instead 0,45-0,9 %.
  • Максимальное содержание железа: 0,30 compared with 0,35 % in 6063 and 0,5 % in AD31.
