But I do appreciate your story about tungsten carbide, too :-)

I'd wager they're fully aware of the differences between tungsten carbide and pure tungsten, having done a doctorate about it.

This actually seems to apply to most of their products. Not just the spheres.
If you search Amazon for "pure tungsten", you'll find vendors selling cubes that are at least more pure than this vendor's stuff. There are also other items that claim to be high purity tungsten.
