Does tungsten float?
No
19,250 kg/m³ against water's 1,000
Tungsten sinks. At 19,250 kg/m³ it is 19.25 times denser than water.
Why
Floating is decided by density alone — mass divided by volume — compared against the fluid. Weight has nothing to do with it directly: a 200-tonne ship floats and a 2-gram pebble sinks, because the ship encloses enough air to bring its average density below that of water. That is also the only reason a steel hull works.

Common questions
- Does tungsten float in water?
- No — at 19,250 kg/m³ it is denser than water's 1,000.
- Does weight decide whether something floats?
- No, density does. A 200-tonne ship floats and a small pebble sinks, because the ship encloses enough air to bring its average density below water.
