Hexavalent Chromium Surface Treatments: Redefining Metal Finishing Standards

Revolutionising Metal Protection with Hexavalent Chromium Treatments

In the world of metal finishing, providing superior protection against corrosion, wear, and thermal stress is crucial. The adoption of innovative solutions like Hexavalent Chromium processes can lead to remarkable improvements in the performance and longevity of various metal components. At Hard Anodising Surface Treatments Ltd, we have fine-tuned these processes, offering bespoke services like Alocrom 1200 conversion coating and Sodium Dichromate sealing, setting new standards for excellence in the metal finishing industry.

Cutting-Edge Solutions for Optimal Performance

Alocrom 1200 and Conversion Coating

The Alocrom 1200 conversion coating is a specialised treatment involving Hexavalent Chromium. It provides an excellent corrosion-resistant layer on aluminium substrates. When low electrical resistance is needed alochrom 1100 is to be used.
When anodising is not permitted, AND when hexavalent chromium is not permitted, specifications suggest Surtec 650V or Irridite NCP.

Sodium Dichromate Sealing

Our Sodium Dichromate sealing process serves as the perfect finishing touch on freshly anodized surfaces. This treatment effectively seals the porous oxide layer created during anodising, enhancing the corrosion resistance and overall durability of the part. The sealing process also provides added resistance to wear and thermal stresses, ensuring the component maintains optimal performance over time.

FAQs

What benefits can Hexavalent Chromium treatments offer?

Hexavalent Chromium treatments provide superior protection against corrosion. Aluminium chromate is the product of the reaction of activated, desmutted aluminium and chromium ion. This is far more chemically reactive than the thin natural oxide found on aluminium. If your aluminium component has areas where no anodising is permitted, chemical conversion may be of benefit.

Why choose Hard Anodising Surface Treatments Ltd for Hexavalent Chromium treatments?

Our wealth of experience and commitment to innovation ensures we provide top-tier Hexavalent Chromium treatments. We leverage our expertise to tailor our services to meet the unique needs of each client, resulting in solutions that provide optimal results.

Are these treatments applicable to various types of metals?

Our Hexavalent Chromium treatments such as Alocrom 1200 conversion coating are primarily designed for aluminium substrates. However, our team is always on hand to discuss the potential applicability of these treatments to other types of metal substrates.

How does Sodium Dichromate sealing enhance anodised surfaces?

Sodium Dichromate sealing provides an effective protective layer on freshly anodized surfaces, enhancing their resistance to corrosion, wear, and thermal stresses. This can contribute to improved performance and extended service life of the anodized parts.
