It's very dense and has a very high melting point. There's a rough sort of lower bound on mass, determined by the thickness of the atmosphere. The projectile needs sectional density greater than that of the atmosphere it's passing through. If it's made of tungsten passing through Earth-like atmosphere, that it would be ideal if it were on the order of a metre long, or longer. The width should also be at least about 1/20th of the length. Putting those together, the minimum useful mass would be about 50 kg. Arbitrarily larger masses are possible, depending upon how much death and destruction they have to cause and the capabilities of the launcher. - Tim
