Scientists Created a New Aluminum Alloy for Future Cars

Scientists of MISIS have developed a new aluminum alloy with the addition of calcium and titanium, which has increased heat resistance and wear resistance. According to the university rector Alevtina Chernikova, in the future, light and durable parts for the machine-building industry can be created from the new alloy.
In production, alloys of aluminum and silicon are widely used, however, due to low plasticity, they are not able to withstand impact loads and complex deformations. MISIS scientists have created an alternative.
"We discovered a new compound including aluminum, calcium and titanium. During the solidification of the melt, a triple compact phase is formed instead of coarse and brittle crystals that impair the deformability of alloys," said D.Sc. Evgenia Naumova, Associate Professor of the Department of Metal Forming at MISIS.
"During the solidification of the alloy, a structure is formed in it, which we call a 'natural composite'. It can be compared to a reinforced material: the tiniest hard particles are evenly distributed in a plastic aluminum base. Hardness naturally increases with the increase in the proportion of these particles. The optimal combination of properties was demonstrated by alloys containing 0.5% titanium," added D.Sc. Nikolay Belov, Chief Research Scientist of the Department of Metal Forming at MISIS.
The university will participate in the International Specialized Exhibition Metallurgy.Litmash'2026 from May 26 to 28, 2026 at the Timiryazev Center in Moscow.
