What Is the Difference Between Chrome and Chromium?

Sep 19 2018Hexavalent chromium is extremely toxic so trivalent chrome or tri-chrome tends to be more popular for modern applications In 2007 hexa-chrome was banned for use on automobiles in Europe Some chrome for industrial uses remains hexa-chrome because the corrosion resistance of hexa-chrome plating tends to exceed that of tri-chrome plating Get price
