The technology of production of heat-resistant aluminium alloy from secondary raw materials was created

The breakthrough achieved by scientists was reported by the Press Service of the Ministry of Science and Higher Education of the Russian Federation; specialists of the National University of Science and Technology “MISIS” have patented a heat-resistant aluminum alloy that retains its strength properties after heating up to 400 degrees Celsius and can be produced from scrap metal. The new technology makes it possible to obtain a material with the required properties without complex and expensive processing methods.

Traditional aluminum alloys, widely used in aviation, automotive and building construction, have a number of significant disadvantages: they lose strength at temperatures above 250°C, their production requires expensive primary raw materials and multi-stage processing.

Researchers at MISIS University have found an original solution. The new alloy, called ALTEK, is created from old aluminum cans and wire, but it surpasses many analogues in terms of heat resistance. The secret lies in a special composition and technology. Scientists have added copper, manganese, iron, silicon, magnesium and zinc to aluminum to form nano- and micro-sized particles during annealing, increasing the strength of the material. The technology eliminates energy-consuming steps such as homogenization and quenching, and makes it possible to produce alloys that are 95% recycled but contain all the required alloying elements.
