【SMM Aluminum Flash News】Purdue Develops Cobalt-Aluminum Alloy with Up to 10 Times the Strength of Steel
Researchers at Purdue University have developed a new cobalt-aluminum (CoAl) intermetallic alloy that combines ultra-high strength with improved ductility. The material achieved a yield strength of 6 GPa, around 6–10 times stronger than high-strength structural steel, while sustaining 15% plastic strain under room-temperature compression. The breakthrough overcomes the brittleness traditionally associated with intermetallic compounds and could support next-generation aerospace, turbine, energy, and defence applications.
