A research team at the National University of Science and Technology MISIS (NUST MISIS) has developed an aluminum-based alloy for use in the creation of electrical systems. This was reported by the university's press service.
The new material is 20 times more ductile than its analogs.
The approach we proposed allowed us to create a material with a fine-grained structure, which, together with the pressing technology used, ensured high ductility of the material. This set of methods significantly improves the physical and mechanical properties of alloys compared to traditional aluminum processing technologies.
It was noted that copper-based materials are now more often used in the creation of electrical systems than aluminum. The latter conducts heat worse. However, Russian scientists managed to solve this problem.
By alloying the alloy with calcium and zirconium, we achieved an optimal balance between the complex of properties of electrical conductivity and heat resistance. Manganese has a significant impact on the increase in electrical resistivity, the addition of calcium provides an optimal phase composition, and zirconium increases heat resistance, while the low iron content in the alloy with manganese will reduce the cost of alloying in the future.
It is expected that the development will expand the use of aluminum alloys in the production of transformers, cables, and other electrical systems.
Earlier, www1.ru reported that a technology for 3D printing of heat-resistant alloys was created in Yekaterinburg.
