In Russia, they created a durable alloy for the aircraft and automotive industries

Russian experts from NITU MiSiS have created a new aluminum alloy that can be used in aircraft and automotive industries. The substance turned out to be more plastic and durable than the analogues existing today.

It is worth noting that aluminum and its alloys takes the second place in terms of scale after steel. This metal has a number of advantages, such as: lightness, corrosion resistance, strength, ductility, etc.

The use of sheet superplastic molding (SPF) allows to obtain integral parts of complex design from aluminum alloys. However, given the fact that most materials used for SPF are characterized by a low deformation rate and elongation of up to 300%, quite a lot of time is spent on the manufacture of the final part. This ultimately affects its value, 70-80% of which falls on technological process.

Scientists from NITU MiSiS managed to get the type of aluminum alloy, which is 20-30% stronger than analogues, and its allowable degree of deformation exceeds 400%. At the same time, it will take only 15-20 minutes to manufacture a part from this material by SPF, which significantly reduces the process and the final cost of the product.

According to the assistant professor of NITU MISiS, Anastasia Mikhailovskaya, due to the properties of the new alloy, it will be possible to manufacture parts of complex shape on equipment of relatively low power.

In the near future, scientists will begin testing a promising material in the production of sheets and will get an international license. Then, the alloy can be introduced into production.

    And what prevents the introduction of a good alloy in domestic production and in parallel to receive an international license?

      ... will begin to test promising material in the production of sheets.

      Will it go into domestic production without testing?

      It is necessary to introduce all the latest scientific achievements, first of all, into the domestic industry and the military-industrial complex, and not to chase the recognition of our scientific achievements by the Western world and not sell them over the hill until they are fully mastered and implemented in Russia, it is time to master our technologies , and not mindlessly buying them abroad, as has been done since the beginning of the 90s !!!
