Re: Densities

[P van Rooyen <rooyen@aib-vincotte.nl>]

I did a quick search fro Tungsten 

if you look at

http://www.kulitetungsten.com/typprop.html

they say 
17,0 g/cm ^3  (90%W) 
up to 18,5 g / cm^3 (97% W)
 
or:
http://www.mi-techmetals.com/refractory.htm
they show several W-alloys with lower %W and with lower density values

but at 
http://www.teledynetungsten.com/mainframe.html
you can read that  89% 97% alloys are used for shielding
