Dural angle is made of aluminum alloy, alloyed with copper 4 - 5%, a small amount of manganese, 0,8% - 1% and magnesium about 2%. Thanks to a balanced combination of components, the material acquires strength while retaining the lightness of aluminum. Sometimes additional components, such as graphite, are introduced into the composition. To increase strength, the alloy is subjected to rapid cooling after hardening, and then at ambient temperature is kept for several days. But the material partially loses its resistance to corrosion. Therefore, for critical components it is additionally clad - coated with a thin layer of aluminum - to improve resistance to external weathering.


The following grades are used: D1, D18, D16, D19, V65, VAD. Manufacturing is regulated by GOST 8617-81 or 4784-97. Corners are produced by hot or cold rolling, sometimes milling is used. A distinction is made between equal-shelved angles, when both sides of the angle is the same, and the angle is not equal. The dimensions of the flanges - from one centimetre to 12 cm. the thickness of the metal is from 1.2 to 3 mm. The length can be up to 12 meters. At the company from the produced batch is sampled to check for microcracks, irregularities, compliance with dimensions and surface finish.

Advantages of

Low weight, strength, good manufacturability. Dural corners are easy to install, connected with other materials by welding. Another important advantage is a low price. These advantages allow the use of dural corners in almost all areas of industry or construction. The most complex constructions can be made of it. Due to the low weight, the structures have a high specific strength.


In construction, dural corners are the basis for prefabricated structures, greenhouse frames, winter garden frames, door and window frames, as well as airframe and light ship frames. Most often duralumin angles of D16 alloy grade are used. The main parameters are presented in the table below.
