For a new project, I bought some tungsten foil that is .002" thick.
It is expensive.
When I opened it and held it up, I thought this is so stiff and heavy
it sure seems much thicker but we measured it and it is .002". Of
course Tungsten has a density of about 19 so I knew it would be heavy
but the stiffness exceeds what I expected. Of course, it is also a
hard material.
Where in boating do we need very thin, very hard and very dense metal?
