35 lb tungsten "ballast" blocks (race cars): $1877

Twice as dense as steel & 50% more than lead, but what a price to pay
for the little space that it saves.

I used to work at an aerospace company that made extensive use of
tungsten weights in an assembly that had to be balanced just so, and was
a 5.000 pound bag with 4.999 pounds of s**t in it.

Sometimes they could use brass.

When the assembly costs enough, a few chunks of tungsten aren't that much
by comparison.
