Possible alternatives for chromium trioxide as a plating agent for use in general manufacturing

One of the goals of the European REACH regulation is the progressive replacement of substances of very high concern (e.g. carcinogens) by safer alternatives. Companies that use these substances, actively search for safer alternatives (less dangerous substances, new technologies and processes), and report about these alternatives. Below you will find the information on possible alternatives for chromium trioxide, included in the different applications for authorisation received so far by ECHA. To obtain further details, please follow the link to the full dossier.

Below you can find possible alternatives for chromium trioxide as a plating agent for sanitary materials. All alternatives refer to the chromium trioxide described below.

Chromium trioxide

  • EC-number: 215-607-8
  • CAS-number: 1333-82-0
  • Use: The use of Chromium Trioxide in chrome plating of objects
  • Technical function: Plating agent for use in general manufacturing

Most promising alternative:

  • Trivalent chromium (CrIII) plating

Other Alternatives:
Different (groups of) companies have researched possible alternatives to replace chromium trioxide. Even if these alternatives may not have been chosen for their particular case, they may still be an appropriate option for other cases.

  • Physical Vapour Deposition (PVD)
  • Chemical vapour deposition
  • Nickel alloy electroplating
  • Electroless Nickel alloy plating
  • Chromium (III)-based plating with nickel sublayer
  • Drum coating
  • Powder coating, melting phase
  • Powder coating, thermal spraying
  • Vacuum deposition of thin films
  • Thermal treatment – Case hardening
  • Digital printing as substitute of the RSP technology

More detailed information

All research efforts by companies have been documented in reports. The following ECHA-dossiers are available about possible alternatives for chromium trioxide as a plating agent for sanitary materials:
