Duraluminous channel is made of aluminum with copper, manganese, and a small amount of magnesium. To alloy acquire the necessary physical and technical properties, it is heated to 500 - 600 degrees, and then subjected to a sharp cooling. The alloy is then left at room temperature for several days, which greatly hardens it. It is used to manufacture a range of fasteners.

This semi-finished product is made of grades D1, D18, D16, D19, B65, BAD by deformation (cold pressing) or hot rolling. According to the type of treatment the material may be soft - made by annealing, hardened and artificially aged to give additional strength. According to the accuracy, they are produced with normal, high or high accuracy. The quality of production of this type of product is regulated by GOST 21 488-97. There should be no scratches, cracks or other damages on the surface of the channel.

Duralumin channel has a minimum weight and sufficient strength. It is cheap, widely used for fasteners for various metal structures. If it is further coated with a thin layer of aluminum or oxidized, it increases its resistance to corrosion. Due to its plasticity, it is easy to work with. It can be well welded to other materials by means of spot welding.


Transport engineering, aerospace industry, shipbuilding, construction, manufacture of lightweight metal structures. Used dural channel also in the design of small architectural forms, in the manufacture of furniture and other areas of the economy.
