Alochrom / Iridite

At E.V.Wood (anodising) Ltd we offer two conversion coatings. The first, Alocrom, is a chrome based conversion coating producing a gold / brown colour.  The second conversion coating is an iridite equivalent which is chrome free (food Safe) and provides a clear coating.  This chrome free coating was developed in response to the ELV, RoHS and WEEE directives and does not contain lead Cadmium, Chromium, Mercury, PBB or PBDE compounds.

These conversion coatings are  a non-electrolytic method of protecting the aluminium surface.  These are conductive of electricity and therefore useful in applications in electronic industries where the component needs to retain its electrical conductivity but also be protected against corrosion. In addition this conductivity means it is an excellent pre-treatment for painting and powder coating processes.


The maximum dimensions we can handle are 1500mm x 600mm x 800mm.
