Technical characteristics

Duralumin is an alloy of aluminum (94%), copper (4%) and magnesium (1%). To buy high-quality duralumin bar it is necessary to make sure that its composition, production process and processing precisely comply with GOST requirements. These are the parameters that determine physical and mechanical properties of the alloy, as well as its characteristics in conditions of low and high temperatures. The main advantages of the material are:

- high strength;

- thermal resistance;

- low volumetric weight;

- excellent weldability by spot welding.

Percentage composition of alloy D 16

Fe Al Cr Mn Cu Zn Mg Si Ti+Zr Impurities
≤0,5 91-94,7 ≤0,1 0,3-0,9 3,8-4,9 ≤0,25 1,2-1,8 ≤0,5 ≤0,2 ≤0,15

Circle D16 is characterized by high ductility, perfectly processed by cutting, excellent hardening with heat treatment, but with increasing strength - reduced ductility and toughness. The marking is fully consistent with unplated dural without heat treatment. Corrosion resistance improves considerably after cladding. Marking D16T denotes a hardened as well as naturally aged alloy. It is in demand in aviation, sea and river shipbuilding, geological prospecting.

The percentage composition of the alloy is B 95

Advantages of

Circle grade B95 has a very high ductility, excellent welding, for example, by means of spot welding. Heat treatment and cold deformation are used to harden the finished product. Plating with pure aluminum greatly improves corrosion resistance. Cuts that are artificially aged and quenched for maximum strength are referred to as B95T1. After quenching, the products must not show any signs of overburning. They are subjected to all the necessary tests immediately after heat treatment. Accuracy of workmanship, strength is normal and the quality of the surface finish is standard.


Transport engineering, fuel energy, construction of industrial structures. The main advantage of this material is the high specific strength at low weight. Loaded structures that work in compression, such as aircraft frames, truck frames, fragments of building facades, are made of this circle.
