Iridium is a hard, silvery-colored metal. It is almost as unresponsive as gold. It has a very high density and melting point. Iridium is the most corrosion resistant material known. It is used in special alloys and forms an osmium-containing alloy used for pen tips and compass bearings. It is used to make the standard meter rod, which is an alloy of 90 percent platinum and 10 percent iridium. It is also used for contacts in spark plugs due to its high melting point and low reactivity.

Iridium has low biological toxicity.
Iridium is one of the rarest elements on earth. It is found uncombined in nature in sediments in rivers.
There is a very thin iridium layer in the earth's crust. This is thought to be caused by a large meteor or asteroid hitting the earth. Meteorites and asteroids contain higher levels of iridium than the earth's crust.
Iridium is used to set standards for weights and measures because it is corrosion resistant. However, because it is so dense and brittle, it is difficult to machine, shape or work unless heated to extreme temperatures.
Today, iridium is recovered commercially as a byproduct of copper or nickel mining.
In the tests and analyzes carried out in our organization, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Among the numerous tests carried out in this context, there are iridium (Ir) testing services within the framework of elemental analysis.
