Iridium pi se sitou itilize nan alyaj, epi li se raman itilize pou kont li. Lè iridium yo itilize pou kont li, li jeneralman nan fòm la nan ingot, cruible oswa fil. Se gwo pwi oblije travay sou iridium nan fil, ak pri fil iridium se sou 1000 RMB / g nan mache a. Alloy nan iridium ak platinum (10% nan Ir ak 90% nan Pt), ak koyefisyan ekspansyon ekstrèmman ki ba, jeneralman yo itilize pou manifakti entènasyonal mèt estanda, osi byen ke mèt kilogram nan mond lan.

Pure iridium is mainly used in alloy, and is seldom used alone. When iridium is used alone, it is generally in the form of ingot, crucible or wire. High cost is required to process iridium into wire, and price of iridium wire is about 1000 RMB/g in the market. Alloy of iridium and platinum (10% of Ir and 90% of Pt), with extremely low expansion coefficient, is generally used for manufacturing international standard meter, as well as kilogram meter in the world.
