Listed below are the grades and merits of the material, as well as its intended application. This information will make it much easier to choose when searching for a structural solution.

Supporting structures

For load-bearing structures, strength is primarily important. High-strength alloys - D16T, D1T, B95T (T1), AK4-1T, AK6T. Medium-strength alloys are АМг5Н, АМг6Н, АД31, АД33. Joining method. All makes except D16 and other dural grades are connected by welding. Threaded connections are used for connection of AK4-1Т, AK6Т, D16Т, АМг5, АМг6, В95Т (T1). Corrosion resistance. High - АМG, АМц, АД31, Д35, АД00-АД1, А0-А5. Low - requires protective coating: B95, D16.

If the material is less strong design strength is achieved by selecting a larger cross section of profiles or larger diameter pipes. But in this case, the weight and cost of the structures increases, and the choice of light and cheap aluminum alloys as a construction material is lost.

Duralumin

D16 grade is one of the most convenient structural grades. The matter is that Duralumin easily deforms after heating up to 500 °C, but the main thing is that in 96 hours after cooling at normal temperature the material regains its initial strength. Angle, pipe, profile can be bent at desired angle without losing its strength. The disadvantage of duralumin is that it can only be welded by spot welding and is prone to corrosion. Since argon-arc welding weld is prone to cracking, duralumin sheet is usually connected by rivets, and pipes - by threads.
