Duralumin circle is called a solid profile with round cross section. Is made of any diameter or length from brands such as B95 and D16. Production rates are regulated by GOST 21488−97. The chemical composition shall comply with GOST 4784−97. The production is normal, elevated and very high precision. Sampling for chemical composition control is made according to GOST 24231−80.

Circle brand V95 has a very high ductility, excellent weldability, for example by spot welding. For hardening of the finished products used heat treatment and cold deformation. Plating pure aluminium improves the corrosion resistance. Circles, artificially aged and hardened for maximum strength, denoted as В95Т1. After quenching the product must not have any trace of burnout. They pass all the necessary tests immediately after the heat treatment. Precision manufacturing, durability are normal, the quality of surface finish — standard.
Circle D16 has a high plasticity, fine cutting, fine hardened with heat treatment, however, with the increase in strength decreases the ductility and toughness. Labeling fully complies with replacerange duralumin alloys without heat treatment. Corrosion resistance is significantly improved while plating. Marking D16T is denoted tempered and naturally aged alloy. He claimed in the manufacture of aircraft, drill pipes, and marine and river fleet.
The mechanical engineering industry, fuel industry, construction of industrial structures. The main advantage of this material is very high specific strength at low weight. From this range are made of high-loaded structures, which work in compression, such as frames of airplanes, trucks, fragments of building facades.
