How about the original article?


Importantly, the researchers were able to achieve this high current density 
tolerance without sacrificing the electrical conductivity of the material, 
which is similar to that of pure copper.

"This is the first such material, to the best of my knowledge, that can have 
high electrical conductivity and high current density tolerance," 
Subramaniam points out.

Then there is this publication.

You understand this is a *new* material they are talking about, no?  The 
focus of the research seems to be on uses for conductors in integrated 
circuits where other aspects than conductivity are limiting.
