What is iridium made from?

Today, iridium is still obtained from platinum ores and as a by-product of mining nickel. Pure iridium is very brittle and is nearly impossible to machine. It is primarily used as a hardening agent for platinum. Iridium is also alloyed with osmium to make the tips of fountain pens and compass bearings.

Is iridium harmful to humans?

What are some interesting facts about Iridium?

Facts About Iridium. Iridium is a very hard, brittle and dense metal and is also very rare. Iridium is the most corrosion-resistant element on the Periodic Table of Elements. It also has the highest density of all the elements. Because it resists corrosion, it is used to set standards in weights and measures.

Where can iridium be found in nature?

Iridium is found in its pure native form and in osmiridium, a natural alloy of iridium and osmium. Iridium is mined from sulfide layers in mafic igneous rocks where it is present with other platinum-group elements. Most iridium is mined in Canada, Russia and South Africa.
