we have two types of chromate conversion coating with respect to the chromium.

  1. Hexavalent chromium conductive coating Cr6 also termed as iridite or alodine
  2. Trivalent chromium conductive coating Cr3 also termed as surtec 650


  • Hexavalent is available two colours golden yellow and clear(transparent)
  • Trivalent is availabe with clear
