Aluminum profiles according to GOST 8617-81

General purpose profiles

GOST 8617-81 applies to extruded profiles of aluminum and aluminum alloys, But not all, but only profiles general purpose. Extruded profiles from aluminum alloy Ad31 (6060, 6063Extruded profiles from aluminum alloy Ad31 (6060, stained glass, marts, Extruded profiles from aluminum alloy Ad31 (6060, GOST 22233-2001.

GOST 8617-81 defines the following requirements for extruded aluminum profiles (the numbering of sections does not match the numbering of sections in the standard).

Classification of aluminum profiles

Profiles are classified according to the type and condition of the material..

1 defines the following requirements for extruded aluminum profiles (the numbering of sections does not match the numbering of sections in the standard)

1) solid profiles with a cross-sectional area up to 200 cm2 and a circumscribed circle diameter up to 350 mm;
2) solid profiles with a cross-sectional area up to 60 cm2 and a circumscribed circle diameter up to 250 mm.

2 ) solid profiles with a cross-sectional area up to

  • without heat treatment (hot-pressed - without additional designations;
  • annealed - M;
  • hardened and naturally aged - T;
  • hardened and artificially aged - T1;
  • incompletely hardened and artificially aged (hardening on a press) - T5.

3 incompletely hardened and artificially aged (hardening on a press) - T5

  • incompletely hardened and artificially aged (hardening on a press) - T5
  • high strength - PP.

assortment

incompletely hardened and artificially aged (hardening on a press) - T5

  • standard profiles incompletely hardened and artificially aged (hardening on a press) - T5, channel bars, stripes, brands, etc.. P.); the shape and dimensions of these profiles, cross-sectional areas, the diameters of circumscribed circles are defined in the assortment standards (more than ten standards);
  • profiles according to customer drawings.

Limit deviations

Technical requirements

1 Profiles are made of aluminum and aluminum alloys in accordance with GOST 4784-97:

  • AD0, AD1, ADS, FROM
  • AMC, AMCs
  • AMg2, AMg3, AMg3s, AMg5, AMg6
  • AD31, AD33, AD35, AB

2 Mechanical properties of profiles

2.1 Material states:

  • without heat treatment - without designation;
  • without heat treatment - without designation;
  • without heat treatment - without designation;
  • without heat treatment - without designation;
  • not fully hardened and artificially aged (hardening on a press) - T5.

2.2 not fully hardened and artificially aged (hardening on a press) - T5

  • not fully hardened and artificially aged (hardening on a press) - T5
  • yield stress 0,2;
  • relative extension.

2.3 It is allowed to manufacture profiles from AD31 alloys, 1915, 1925 without heat treatment instead of the “hardened and naturally aged” condition provided, that the mechanical properties of the profiles meet their requirements for this state.
2.4 Requirements for the surface quality of profiles
2.5 Requirements for the macrostructure of profiles for non-metallic inclusions
2.6 not fully hardened and artificially aged (hardening on a press) - T5, not fully hardened and artificially aged (hardening on a press) - T5.
