In spite of the potential risks associated with the consumption of even small amounts of chromium-6, both chromium in general and chromium-6 in particular provide important benefits to society.  Chromium has corrosion resistance properties that are superior to most metals making it a common choice for both metal alloys and corrosion resistant coatings.  United States Patent 7,175,667, listing Gerald Saunders of Ontario as the first named inventor, teaches that a bio-compatible alloy made of Cobalt-28, chromium-6, and molybdenum is the preferred material for use in a surgical implant method.  United States Patent 7,799,429, listing Ga-Lane Chen of Santa Clara, CA as the first named inventor, teaches the use of chromium nano-particles in combination with super-hard nano-particles such as silicon carbide to make a hardened corrosion resistant coating surface.
