According to Torgom Akopyan, a senior researcher at NUST MISIS, the new alloy of aluminum, copper, calcium and silicon is a promising material for the aviation industry. It can replace expensive industrial aluminum alloys used in pistons and aircraft engines.
The new technology makes it possible to replace rare earth metals with calcium, significantly reducing production costs. The result is the formation of insoluble crystals that improve the mechanical properties of the alloy while preserving its workability.
