Alocrom plating is a chrome conversion coating used to plate aluminium and increase corrosion resistance. It creates a pre-paint finish and good adhesion qualities. There’s many benefits to Alocrom which include:

  • Corrosion resistance
  • Excellent paint and power bonds
  • Can withstand heat after coating
  • Can self-heal if scratched
  • Low electrical resistance

However, alocrom plating is not suitable for decorative effects as a change in colour may occur.

What can alocrom plating be applied to?

Alocrom is chemically applied to aluminium. Here’s a type of Alocrom:

  1. Alocrom 1200 is also ideal for protection against corrosion to both unpainted and painted aluminium. It forms a protective golden coloured chromate coating on aluminium and alloys and has a more visible colour change.

What is the alocrom plating process?

Alocrom plating is applied by dip or spray washer to give a uniform coating.

The aluminium will be thoroughly cleaned to remove all oil, grease and oxide coatings. It is then dipped into the alocrom solution, and after 1 – 5 minutes the coating will show up as a golden yellow. It is then rinsed with clean water and dried.

What is alocrom plating used for?

Alocrom plating is mostly always used as a pre-paint treatment and for increasing corrosion resistance, making it ideal for coating aluminium and high silicon pressure die-castings. It is used for:

  • Tools within general industrial work
  • Electrical components
  • Household appliances
  • Car parts
  • Aerospace components
