Duralumin appeared at the beginning of the 20th century. It was named after a small industrial German town where it was first melted in a metallurgical plant. Alfred Wilm, a German metallurgical engineer, discovered the possibility of fivefold hardening of aluminum. He did this by adding 4% copper to it and quenched the resulting alloy, followed by a five-day soaking period.


What does the marking D16T mean? D - duralumin, 16 - the average content of magnesium in tenths of a percent, T - heat treatment, to increase the strength characteristics the metal was subjected to hardening and natural aging. Duralumin semi-finished products are marked as follows. normal cladding - A, technological cladding - B, unclad - have no additional designation. The quality of finishing is standard, strength and accuracy of manufacturing is normal. Allotted by the state of the material: hot-pressed - without additional heat treatment, as well as hardened and naturally aged - T. Products that have undergone hardening, should not have signs of burnout. After termination of heat treatment dural samples are tested. Dural pipe looks like a hollow profile of different cross-section. GOST 18482-79, 18475-82, 23697-79 regulate production of D16 alloy tubes. GOST 4784-97 specifies chemical composition.

Basic qualities

Dural semi-finished products are malleable, lightweight and very easy to spot-weld. To achieve corrosion resistance, the material is clad with pure aluminum. Cold deformation makes the material very hard, and annealing makes it ductile and workable. Dural semi-finished products are lighter compared to steel, last longer and are cheaper.

- material hardness - up to 42 MPa;

- Operating temperature limit - up to 230 ° C;

- tensile strength - 440 MPa;

- yield strength - 300 MPa.

It is worth noting that elongation after rupture can reach 20%.


For reliable lightweight structures, dural sheet and section steel is indispensable. When creating food equipment, frames of high-speed trains, airplanes, cars - it is very popular. Duralumin pipe is often used for fragments of facades, laying pipelines for special purposes. Manufacturers of oil equipment need duralumin pipe. Its operational characteristics allow to guarantee uninterrupted use of a well for 8 years. Duralumin pipe and sheet are in demand in aviation and automobile industry, practically irreplaceable in production of road signs and billboards. Duralumin wire is no less popular at the market; its main consumers are the fuel and chemical industries. To improve corrosion resistance, dural rolled steel is usually clad, and for pipes, oxidation and inorganic inhibitors are used.
