Russian scientists have created an aluminum alloy that can withstand temperatures of 400 ° C

A joint group of scientists, consisting of representatives of NUST MISIS, MSTU named after G. AND. Nosov, Siberian Federal University, as well as the NRC "Kurchatov Institute" announced the successful development of an inexpensive aluminum alloy, which was able to withstand temperatures up to 400 degrees Celsius. This, for a minute, is about 100-150 degrees more than existing analogues can withstand. It is about this discovery and its prospects that will be discussed in this material.

Aluminum and its role in the modern world

At the moment, aluminum is actively used in aviation, motor transport, energy, etc. And all because both aluminum itself and alloys created on its basis have an increased corrosive resistance in almost any environment: atmosphere, water (sea and fresh), various chemicals and food.

In addition, aluminum (and its alloys) has a low specific gravity and excellent thermal and electrical conductivity.

That is why aluminum alloys are quite promising. After all, they may well replace the more expensive and heavier copper, for example, in airplanes, high-speed rail transport, etc.

But the previously known aluminum alloys were quite expensive to manufacture, and they did not have the proper characteristics in terms of heat resistance.

Russian scientists have proposed a new algorithm for producing an aluminum alloy (in which, in addition to directly aluminum itself, copper, manganese and zirconium are also included), as well as production from a new aluminum alloy wire.

The engineers proposed a method of electromagnetic casting with subsequent processing, including deformation-heat treatment, drawing and annealing.

In the process of work, an electromagnetic crystallizer was used in conjunction with the ElmaCast technology, which was developed by the "Scientific and Production Center Magnetic Hydrodynamics". The result is an alloy that can easily withstand heating up to 400 degrees Celsius with high electrical conductivity and strength.

Scientists are still working on improving the technology, but they already say that in the future their alloy may find the widest application in many areas of industry.

The scientists shared their work on the pages of the Journal of Alloys and Compounds.
