ELI5: Would a boat made of tungsten float on lava?

Recently I just thought that if a boat were to be made of tungsten, or another metal that can't be melted by lava, would it float on lava?
gpt
Actually, it probably could. Metal boats are made in such a way that their average density seems lower than that of the metal simply because the hull is filled with air, reducing the density. The melting point of tungsten is also way above that of the normal temperature of lava, so yea.
