Product Code : ME-Ir-5N-SF
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 Iridium High Purity Foil and sheets in many thicknesses and sizes for numerous industrial uses and provides health and occupational safety information for this product. Most foils are produced from cast ingots for use in coating and thin film 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), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thickness can range from 0.003" to approximately 2mm for all metals. Some metals can also be rolled down as thin as 0.001" for use as an evaporation source in microelectronics, optics, magnetics, MEMS, and hard resistant coatings. Piece sizes are available up to approximately 7" maximum width. Maximum lengths of about 20" can be obtained with a nominal thickness between about 0.005" and 0.020" for thin film deposition on glass or metal substrates.

Applications of Iridium Foil
It is extremely corrosion resistant and is used as an alloying agent with metals such as gold and osmium to produce alloys which are extremely hard and have good corrosion resistance.
Packing of Iridium Foil
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 Foil is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
