Yeah Tungsten is very expensive, that is why the H3G buffers are so damned expensive.
Considering the amount of Tungsten that is used in a wide variety of industries and that there is a fair amount of waste involved it could result in a secondary industry which collects and makes use of the scrap.
Using a sintered core could be one use of this widely untapped resource, another would be to smelt it down and pour it into molds in a very rapid foundry type system. Using green sand you could really just keep making mold after mold with nearly no waste at all.
All you need in a positive form to impress into the tray of green sand, a tray for the lid and there you go!
They use the same process for many other things in automotive and shipbuilding industries.
We save our tungsten scrap for use in making weights for other items, you really hate to waste any of it.
