"The reverse sides of medals are usually very similar." W. Grzegorczyk.


According to GOST 21 488-97 - aluminum circle is produced of round cross-section Ø 8-400 mm, from technical aluminum AD0, AD1, AD or alloys AK8, AMC, AD31, AK6, D1, AK4, AK4-1, D16 or others. The standard length is 0.5-6 m. Chemical composition is regulated by GOST 4784-97. Circle with ordinary quality of finishing has a matte surface without delamination, cracks, foreign inclusions, traces of dirt or corrosion. Microstructure of the parts that have undergone hardening - without any traces of overburning. They are tested on completion of heat treatment. Bevel, ovality, twist and curvature are checked in accordance with GOST 26 877-91.

Aluminum round is very light, comparatively cheap and perfectly amenable to mechanical processing. It is non-magnetic, has high electric and thermal conductivity. Thanks to the surface oxide film, it is little susceptible to corrosion in a humid environment. It is non-toxic, durable, aesthetically pleasing and superior to steel in a number of respects:

  • it is a much lighter metal;
  • much more technologically advanced;
  • Aluminum alloys with silicon or magnesium, resistant even to seawater.

Aluminium circle marking

State of the material Strength Rolled precision By length

M - soft, annealed;

T - naturally hardened and aged;

T1 - hardened and artificially aged.

PP - increased strength;

Without designations - of normal strength.

N - normal;

P - increased;

B - high;


KD - multiple of measured length (with a multiplicity designation);

NK/HB - shorter than/no more than specified length with given size designation

BT - coils (of off-gauge length).

Hot-drawn rounds are manufactured without heat treatment.

An example of designation of an aluminum circle: Circle D16T PP KR60Ph4000 GOST 21 488-97 circle of alloy D16, precision manufacturing, glued and naturally aged, diameter 60 mm, increased strength, length 4000 mm:

Duraly circle

Circle grades D16, D16T, B95T1, B95 - GOST 21 488-97 manufactured from duraluminium (chemical composition - GOST 4784-97). Thanks to alloying (additives Cu, Mg, Mn) duralumin has significant fatigue endurance properties, static strength - up to 500 MPa and ductility. Compared to steel, durum is considerably lighter and less expensive. Additional heat treatment (hardening, natural or artificial aging) makes it possible to considerably strengthen such a circle. Since dural products are susceptible to corrosion, a film of pure aluminum is applied to them.


Dural is relevant in transport engineering, when creating lightened strong frame structures of sports cars, ships and aircraft,


Evek GmbH stocks a wide range of aluminum and aluminum alloys. We supply duralumin circles D16T (hardened and naturally aged), D16, B95, B95T1 (hardened and artificially aged).
