I'm tired of articles with titles like "X makes Y bigger/faster/stronger," then never giving an answer to the obvious question: "How much?" This article is happy to tell you it costs $25M to develop , how many hours the annealed the metal, the patent numbers, the years the researchers got their degrees, but never once gives a single number related to the materials performance. Maybe its 0.1% better, maybe its 1000% better. I guess its not important.

There's a few numbers in the Science article, and they do actually link to it, unlike some. [0

And the intro numbers are... Exciting.

> This core-shell structure neither dissolves nor coarsens at temperatures of up to 800°C while also causing the yielding strength to be in excess of 1 gigapascal.

In other words, it makes the copper allow much stronger than mild steels, like the stainless steels, and on par with strong (but by far not the strongest) steel alloys.

Imagine cutting stainless steel with a copper-based blade, and not the other way around.
