They were used a lot in aerospace and military applications. One thing that used to appear on the surplus market was an EOD toolkit used by bomb disposal techs. Even had a beryllium hammer. These were wonderful tools which you might just find when clearing out old uncle Bob's estate...

Oh... where did I put that pile of junk? :->

I have encountered Beryllium in a field none of you mentioned, as
material for speaker cones. Light and very rigid. Perfect for the top
driver for horns. I recall something about high speed of sound.
