Chromate Conversion

Chromate conversion is a process that is used to passivate aluminium prior to painting. It also offers resistance to corrosion while still allowing some electrical conductivity. We are able to work to Defence and American Military standards, proving you with a certificate of conformity for each part processed. At Collings Finishing we offer the following chromate conversion finishes...

  • Alocrom 1000
  • Alocrom 1200
  • Alocrom 407-47
  • SurTec 650

Areas that need to be left raw can be masked or bunged to leave the surface untouched. To find out which is the best finish for your application, please call or email one of our knowledgeable sales team.
