Scientists at the Institute of Non-Ferrous Metals of the Siberian Federal University have developed new compositions of aluminum alloys and combined processing technology for the production of conductor wire used in aviation and the automotive industry. Such a wire has an increased level of heat resistance and electrical conductivity, is more resistant to temperature fluctuations and at the same time cheaper in comparison with existing analogues.
In the course of research, scientists have found that it is possible to increase the electrical conductivity, strength, ductility and thermal stability of samples during operation by reducing the content of rare earth metals in the alloy.
"We have determined the compositions of low-alloy aluminum alloys with a reduced content of zirconium and cerium. The wire produced from these alloys meets international standards due to the optimal combination of rare earth metals," said Vadim Bespalov, head of the study, doctoral student of the Department of Metalworking, Associate Professor of the Department of Engineering Bachelor of CDIO at SibFU.
As the head of the study noted, the developed compositions of heat-resistant low-alloy aluminum alloys and technological production schemes will allow the production of conductor wire with lower economic costs compared with traditional manufacturing methods.
The research was carried out with the financial support of the Russian Science Foundation.
