Yellow Hexavalent Passivation

The Diamond Metal Finishing Co Ltd still applies hexavalent chromium (classified as a special process) products upon request of the client.

However, as the industry is changing, many OEMs have changed their process specification requirements and have begun looking for suitable green replacements. The Diamond Metal Finishing Co Ltd strives to educate clients on the benefits of using our alternative trivalent or non-chromate options and are glad to offer the relevant advice.
