Product Code : ME-Ir-5N-WI
Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, it is considered the second-densest naturally occurring metal (after osmium) with a density of 22.56 g/cm3 (0.815 lb/cu in) as defined by experimental X-ray crystallography. It is one of the most corrosion-resistant metals, even at temperatures as high as 2,000 °C (3,630 °F). However, corrosion-resistance is not quantifiable in absolute terms; although only certain molten salts and halogens are corrosive to solid iridium, finely divided iridium dust is much more reactive and can be flammable, whereas gold dust is not flammable but can be attacked by substances that iridium resists, such as aqua regia.
ATT specializes in producing high purity uniform shaped Iridium Wire with the highest possible density High Purity Metal Wirefor use in semiconductor, Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard Metal Wire sizes range from 0.75 mm to 1 mm to 2 mm diameter with strict tolerances and alpha values (conductive resistance) for uses such as gas detection and thermometry tolerances (Also see Nanoparticles) . Please contact us to fabricate custom wire alloys and gauge sizes. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies.

Applications of Iridium Wire
Iridium wire is the most corrosion-resistant wire known, and is often used for the manufacture and repair of filaments and heaters and electrical applications.
Packing of Iridium Wire
Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
ATTs’Iridium Wire is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
