Some asteroids do have high levels of iridium, but it is not a universal trait. Iridium is found in varying concentrations in different types of asteroids, depending on their composition and origin. The presence of iridium in an asteroid can provide insights into its history and formation.
Iridium is normally found in naturally-occurring alloys, which makes the answer not quite either of those things. Iridium in its elemental metallic state is fairly inert chemically, so it's not completely ludicrous that a "nugget" of iridium might be found ... if there weren't so very little of it (it's one of the rarest elements in Earth's crust), so that it's much more likely to be found alloyed with copper or platinum.
The element that has been linked to the extinction of the dinosaurs is iridium. High levels of iridium have been found in sediment layers around the world from the time of the dinosaur extinction, suggesting that it may have come from an asteroid impact.
26,4 g iridium is equal to 0,137 mol.
"Iridium: The shining choice for elite performance."
After finding Iridium, now he got enough evidence for his theory. That Iridium was from the asteroid that impacted the Earth and caused dinosaurs to perish.
Iridium is a dense, hard, and corrosion-resistant metal. It is one of the rarest elements on Earth and is often found in asteroids. Iridium is commonly used in spark plugs, crucibles, and in the production of specialized equipment like compasses and surgical instruments.

Iridium
Iridium can be found in meteorites and certain types of rocks, as well as in small quantities in the Earth's crust and mantle. It is commonly found in platinum ores and alongside other platinum group metals. Commercially, iridium is extracted as a byproduct of nickel or platinum mining.
Iridium is typically found in nature combined with other metals, such as platinum. It is rarely found in its pure form due to its high melting point and resistance to corrosion. Most iridium is extracted as a byproduct of nickel mining or from meteorite impacts.

Iridium, Einsteinium
I think you are referring to the 'iridium spike' - the Yucatan impactor brought to earth a quantity of iridium that was deposited and is detectable at the K-T boundary (the Cretaceous - Tertiary boundary) wherever this is found round the planet.

Osmium and iridium are the two elements with highest density.
