No, I mean using atomic bombs to manufacture these alloys at scale. In the 50s a-bombs were proposed for all sorts of workaday uses. Imagine using a small a-bomb for mining just as we use ANFO today.
I am sure that somebody will take up the task of reproducing these alloys using intense heat from a non-atomic source. New alloys can be quite lucrative but developing them requires just as much experimentation as making new drugs. I'd imagine that getting to an alloy of 7 metals through progressive experimentation would take awhile. Now we know it's possible and have a possible production path. That is enough to spur some experiments down that road.

Both the US and the Soviet Union actually experimented with "nuclear fracking" in oil/gas fields. The Soviet Union also used atomic bombs to put out fires in gas fields as late as 1981.
