An aluminum circle is a round bar made of various grades of aluminum, as well as its alloys, in particular D16T. The standard circle length is 0.5 - 6 meters, and the diameter is from 8 to 400 mm. Such a circle is a relatively cheap, lightweight material and is easy to machine. Thanks to the oxide surface film, it is resistant to external influences and corrosion. It is non - toxic, durable and has a good aesthetic appearance.

In terms of a number of indicators, such a circle even surpasses steel: for example, in terms of manufacturability, aluminum is one of the lightest metals in the world, and its alloys with magnesium or silicon are very stable in sea water.


Duralumin wheels are produced from the following brands: D16T (analogue of 2024 T4), D16, B95, B95T1. The chemical composition complies with GOST 4784 - 97. Dural is alloyed with Mg, Cu, Mn. Such a circle is characterized by fatigue strength, toughness and static strength up to 500 MPa. Compared to steel, it is cheaper and much lighter. Additional heat treatment of such a circle (artificial or natural aging, hardening) can significantly strengthen it. This material is susceptible to corrosion, therefore, a film of pure aluminum is applied to duralumin products. The dural circle is indispensable in transport engineering: in the structures of ships, aircraft, cars, light and durable frame structures are produced from it.

The aluminum circle is marked and subdivided into the following types:

by sectional shape:

- KR - round;

- KB - square;

- SHG - hex.

по точности изготовления:

- В - высокой точности

- алюминиевый круг нормальной точности;

- П – повышенной точности.

по состоянию материала:

- круг алюминиевый горячепрессованный без термической обработки;

- М – отожженные мягкие;

- закаленные;

- Т - состаренные естественно;

- Т1 - состаренные искусственно.

по классу прочности:

- повышенной прочности – ПП;

- нормальной прочности.

по характеристике длины:

- КД – алюминиевый круг кратной мерной длины (с указанием кратности);

- НБ/ НК - немерной длины (с указанием заданного размера);

- БТ - в бухтах немерной длины.
