An ultra-tough copper alloy that is stronger than steel and can be used to build better airplanes and spacecraft. It can withstand temperatures of 1500 F. This alloy is an excellent candidate to build parts for high-temperature aerospace applications. The researchers published their findings March 27 in the journal Science.
The new alloy, a mixture of copper, tantalum and lithium, was built on nanoscales to withstand extreme temperatures and strains, and will have significant applications for aerospace, defense and industry.
"This is cutting-edge science, developing a new material that uniquely combines copper's excellent conductivity with strength and durability on the scale of nickel-based superalloys," reports study co-author Martin Harmer, a professor emeritus of engineering at Lehigh University in Bethlehem, Pennsylvania.
