Aluminum tape according to GOST 13726-97 aluminum and soft alloys

admin

Mechanical properties of aluminum tapes in accordance with GOST 13726-97 depend on:

  • the chemical composition of grades of aluminum and aluminum alloys;
  • state of the material, i.e. obtained by heat and strain treatment tape.

Below are the requirements of GOST 13726-97 to mechanical properties of tapes made of aluminum and soft aluminum alloys AMts, AMTSS and MM in various conditions.
