To understand why DU makes a good anti-tank weapon you have to enter the Alice In Wonderland world of high-energy collisions. When metal meets metal at five times the speed of sound, hardened steel shatters like glass. Metal flows like putty, or simply vaporises. A faster shell does not necessarily go through more armour, but, like a pebble thrown into a pond, it makes a bigger splash.
Armour penetration is increased by concentrating the force of a shell into as small an area as possible, so the projectiles tend to look like giant darts. The denser the projectile, the harder the impact for a given size. DU is almost twice as dense as lead, making it highly suitable. The other metal used for anti-tank rounds is tungsten, which is also very hard and dense. When a tungsten rod strikes armour, it deforms and mushrooms, making it progressively blunter. Uranium is “pyrophoric”: at the point of impact it burns away into vapour, so the projectile stays sharp. When it breaks through, the burning DU turns the inside of a vehicle into an inferno of white-hot gas and sparks.
