Chromium metal ingot - one troy ounce - .999 bullion Chromium was first isolated in its metallic form in 1797 by the French pharmacist and chemist Louis Nicolas Vauquelin who is cr edited with the discovery of this elemental metal. Chromium is extremely hard, corrosion resistant, and reflective. Chromium has an estimated average concentration in the earth crust of 100 ppm. It is an important component of steel, making it stronger and corrosion resistant. It is also used to electroplate metallic parts due to these properties and its beauty when polished to a high shine (think Harley-Davidson motorcycles). It is used as an additive to preserve wood and tan leather and is also used is various pigments and dyes and is a natural component some of nature's most beautiful gemstones including emeralds and rubies. Inscribed on these ingots are the chemical symbol (Cr), purity (99.9%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our logo. These ingots are lightly polished, similar to the one pictured. There can be tiny edge dings, light surface scratches, light edge grooves and other small imperfections. Weight and purity are guaranteed by Rare World Metals Mint. The metallic form of chromium that we sell is nontoxic though some chromium compounds are considered toxic and carcinogenic.
