Why Tungsten is the Perfect Metal for Bullets and Missiles

Tungsten is almost three times as dense as iron, almost twice that of lead and virtually the same as gold, its high density made itself that earned it is name which is comes from Swedish: tungsten heavy stone.

All sorts of weird applications have evolved to exploit tungsten's unique qualities. As we know, its density could rage from 17.0~18.5g/cm3, and the hardness usually from 24~28HRC, besides, when it comes to be used as the bullet, then the hardness should be controlled at least 40HRC, that is the most important reason why the military has called tungsten into service in another kind of evolutionary arms race, and also it is a prefer material called green bullet for tungsten missiles for it is non-toxic.

Tungsten makes very good bullets, which is the kind of thing that if you fire it at someone else's armour, and it will go right through it and kill it. Just like the creatures of the Cambrian period, once someone starts using teeth (or tungsten bullets and missiles) you need to do something about it. If you introduce tungsten into your bullets you've got to introduce tungsten into your armour. The fascinating balance military engineers have to negotiate between the strength of tungsten and the costs in fuel and manoeuvrability all that extra weight brings.

Now they could put the tungsten on the side of the tank but not on the top. Then people are developing warheads that will fly towards the tank and then at the last minute go up and then drop on it, so then you have to start arming the top of the tank. So tungsten metal is a perfect for bullets and missiles.
