As on Earth, the denser metal separated from silicate material and sank toward the center of the asteroid, forming a core.

Gold is one of the densest metals and therefore much heavier (for equivalent size or volume) than the common metals such as lead, brass, copper and steel that are used to make fake bullion coins.

Smacked in the side of the turret with a dart measuring little more than one inch wide and a foot and a half long, made from the densest metal available to man, the German tank was consumed by a catastrophic explosion.

The densest metals you can find.

The addition of a second metal to copper increases its hardness, lowers the melting temperature, and improves the casting process by producing a more fluid melt that cools to a denser, less spongy metal.

The distance's thrown by male athletes became greater from the 1950s onwards as a result of improved equipment using the denser metals, a switch to concrete throwing areas, and more advanced training techniques.

You specifically stated in those engineering lectures to Fandarel that the antimatter is held out of contact with matter in the densest metals Mankind has ever forged.

In my opinion the solar system is a solid homogeneous body; the planets which compose it are in actual contact with each other; and whatever space exists between them is nothing more than the space which separates the molecules of the densest metal, such as silver, iron, or platinum!

Modern safe locks are made of lightweight materials such as nylon to frustrate this technique, since most safe exteriors are made of much denser metals.
