Heavier than lead?

Is that a material that one can work with, ie melt, heavier than lead? Need for upper barrel of unsingle barrel to balance gun. Lead atomic weight 207, Ununbium 285. Trouble is, no one has yet found away of making Ununbium.

Powdered tungsten carbide, but forget about melting it. Put the powder in some kind of tube or cylinder to contain it kind of like a mercury mule. Non-toxic and about $30/lb. Check with an outfit that does powder coated finishes for a source.

Also atomic number and density are not quite the same thing unless you are dealing with ideal gases.

Ding ding ding, Wolfram has the right answer. Tungsten is nearly twice as dense as lead. The powdered tungsten available from bullet manufacturers (Corbin is one) is great for adding weight in small areas. We use it in competition sailplanes. You can mix it into epoxy and get a heavy slurry that can be applied to all sorts of strange places.

You are correct buzz, normal pyrotechincs won't get close to melting W or WC. It's one of those things I do for a living and I gotta tell you it is the next best thing to going nuclear. 4505F and baby thats 'burnin down the house' hot. And no I can't get you some.
