Cost change from hexavalent to trivalent process?

Yes, in most cases changing from hexavalent conversion coating passivation to trivalent adds cost. The percentage of cost increase is hard to say because it depends on several variables. It can wildly vary from plater to plater. Sometimes I hear 30 or 50% additional cost. In the automotive world, this will be difficult to swallow with high-pressure towards cost-reduction.
