I build boats with tungsten
Hi
"James" skrev i en meddelelse ... Many classes of boat now have it writted in the rules.. something like... "no materials of a specific gravity greater than lead..to be used in any part of the vessel." A decade ago, somone was banned using Uranium 238 in some american cup . Wolfram is way to expensive and difficult to cast , being it's melting temperture round some 3500 deg.C. --------- acturly this is the reson it was used in light bulbs ,as even white glowing it will not melt.
