Iridium metal ingot - one troy ounce - .9995 bullion
Iridium was discovered by Smithson Tennant in 1803 and named after the Greek goddess Iris due to the brilliant colors of its salts. A member of the platinum group metals, iridium is the most corrosion resistant metal, is the second most dense and has the second highest modulus of elasticity (edged out by osmium for both of these properties) and has a very high melting point. It is one of the rarest elements in the Earth's crust with an estimated concentration of 0.001 parts per million (gold is about 40 times more abundant). It is estimated that 3 tonnes of iridium is produced worldwide annually (compared with about 2500 tonnes of gold). It is used in the electronics, aerospace and chemical industries.
Inscribed on our ingots are the chemical symbol (Ir), purity (99.95%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our logo. We have sold out of our most recent batch of Ir which ended with ingot #0075. We plan to have another batch ready in the second half of 2017. In completing our 2016 year end inventory recently, we came across two Ir ingots from our very first batch which we had been saving for potential matched sets of the same serial numbers. The two we have left as of today (Feb 8, 2017) are serial numbers 0009 (pictured) and 0004. These ingots are lightly polished, similar to the one pictured. There can be tiny edge dings and other tiny imperfections which do not detract from the inherent value of this rare precious metal. As always, weight and purity are guaranteed by Rare World Metals Mint. Iridium is not known to be toxic and the solid form we supply is considered safe. Its fine turnings or powder form could ignite in air and can be an irritant to eyes and mucous membranes. As we suggest with all of our metals please keep in a safe place, do not ingest, and keep out of the reach of children.
