American Elements' AE Bullion™ group mints certified high purity Iridium Bars for short and long term physical possession and to allow for exposure and controlled risk to industrial demand fluctuations reflected in the global iridium price. Besides iridium bars, iridium coins and iridium Ingots may be purchased by funds, currency reserves, exchange-traded funds (ETFs), private investors, collectors and hobbyists to take direct physical title and possession of the metal with risk exposure from shortages or chemical/physical technology changes, such as in solar energy, and fuel cell developments, equivalent to movements in the industrial application price of Iridium. American Elements offers bonded short and long term warehouse inventory services for AE Bullion™ coins to investors, funds and collectors who do not wish to take physical custody of the metal or lack secure storage or warehouse capabilities. The lowestEtching of Medieval Minting Equipment and Processes possible bar unit price to Iridium melt value ratio is maintained through state of the art mint and die systems and analytically certified blanks (planchet or flan) refined and pressed to exacting purity and weight. We also produce Iridium as rod, pellets, powder, pieces, disc, granules, and wire, as nanoparticles and in compound forms, such as oxide. Iridium Bars may be purchased in bulk or small quantity. Portfolios of different elemental metal bars or coins may also be structured and purchased from the AE Bullion™ group allowing for strategic risk allocation and indexing across a basket of metals.

Iridium (Ir) atomic and molecular weight, atomic number and elemental symbolIridium (atomic symbol: Ir, atomic number: 77) is a Block D, Group 9, Period 6 element with an atomic weight of 192.217. The number of electrons in each of iridium's shells is [2, 8, 18, 32, 15, 2] and its electron configuration is [Xe] 4f14 5d7 6s2.Iridium Bohr ModelThe iridium atom has a radius of 136 pm and a Van der Waals radius of 202 pm. Iridium was discovered and first isolated by Smithson Tennant in 1803. In its elemental form, Iridium has a silvery white appearance. Iridium is a member of the platinum group of metals. It is the most corrosion resistant metal known and is the second-densest element (after osmium).Elemental Iridium It will not react with any acid and can only be attacked by certain molten salts, such as molten sodium chloride. Iridium is found as an uncombined element and in iridium-osmium alloys. Iridium's name is derived from the Greek goddess Iris, personification of the rainbow, on account of the striking and diverse colors of its salts.
