Here is a conversation I have almost daily at my desk:
Passer-by notices cube: "What is that, it looks cool/awesome!"
Me: "It's a solid tungsten cube"
Passer-by tries to pick it up: "What the #$%# why is it so @#$@ heavy!!???"
70% denser than lead
- Denser than Uranium
- Nearly impossible to melt
4x harder than Titanium
19x denser than water
Tungsten has the highest melting point of any element. In fact, you can't easily build a container to melt it. You have to resort to expensive powder compression methods to form it.
The manufacturing process is truly amazing. A pressure of 60 tons per square inch is used to create the cube in a giant steel press.
Tungsten is an extremely rare element (only 100 parts per billion in the earth's crust).
