Aluminium Conversion Coating

Chromate conversion offers a cost effective non-electrolytic process for coating aluminium resulting in excellent corrosion resistance, a good pre-paint finish and good adhesion qualities.


Aluminium conversion coating is generally found on space / aerospace products or where corrosion protection is required with good electrical conductivity.

Our Expertise

TPG can apply aluminium conversion coatings to a variety of different shaped components. TPG can also apply this process selectively in conjunction with other finishes such as electroless nickel silver etc.
