Duralumin area is made of aluminum alloy, alloyed with copper to 4 — 5%, a small amount of manganese, to 0.8% — 1% and magnesium 2%. Due to the balanced combination of components, the material gains strength, while maintaining lightness of aluminium. Sometimes the composition is administered additional components, for example, graphite. To increase the strength of the alloy after quenching is subjected to rapid cooling, and then when the ambient temperature is maintained for several days. But the material thus partially loses its resistance to corrosion. Therefore, for the manufacture of critical parts, he additionally exposed the cladding is coated with a thin layer of aluminium to increase resistance to external weathering.
Used stamps D1, D18, D16, D19, B65, VAD. The production of normalized GOST 8617−81 or 4784−97. Corners are made by hot or cold rolling, milling is sometimes used. Distinguish the parts of the angle, when the two sides of the same area and angle. The sizes of bins, from one centimeter to 12 cm. of Thickness from 1.2 mm to 3 mm. the Length can reach 12 meters. The produced batch is sampled to check for the presence of microcracks, irregularities, conformity to dimensions and surface finishes.

Dural area due to its alloy is light, toughness, good ductility and easy workability. It is easily connected with other materials by welding. Another important advantage is the low price. These advantages allow the use of area in almost all fields of industry or construction. It can do the most intricate designs. Due to the low weight structures are high specific strength.
The area most widely used in construction. He often serves as a basis for creating any designs. For example, from the skeletons of greenhouses, frames conservatories. Made different parts of doors, Windows, sills. Widely used for decoration. It is also used in the aerospace industry, shipbuilding, mechanical engineering. Most commonly used dural corners brand of alloy D16. The main parameters are presented in the table below.
