Type II & Type III Hardcoat Aluminum Anodizing:
Black and Clear
For the highest degree of wear and corrosion protection for aluminum parts, with even color and thickness distribution, manufacturers rely on Greystone.
Greystone specializes in providing precision, high-volume type II and type III aluminum hardcoat anodizing services at our state-of-the-art facilities in Rhode Island and Virginia.
Greystone anodizing services cater to a diverse range of aluminum alloys, including castings and extrusions for the automotive (including electric vehicles), defense, outdoor recreation and other commercial/industrial manufacturers. Greystone anodizing is customized to your parts in whatever timeframe you need with fast turn times and expediting options.
I have been a steady customer of Greystone for about 9 years. I have tried at least a dozen other vendors for hardcoat anodize. No other vendor has provided me the consistency and quality of finish that I have received from Greystone. Their QC department is excellent, often finding issues that I did not catch prior to shipping off to anodize. Any parts that they do find that have excessive machine marks or other imperfections are always marked so that I can easily sort when I receive them. Their loss rate due to process issues is virtually non-existent. Logistically they are one of the best vendors I have. POs always ship complete and on time. Invoicing and payments are handled with no issues. Everyone who asks for solid source for anodizing gets referred to Greystone.

Understanding Anodizing
Anodizing is an electrochemical process that significantly improves the surface properties of aluminum, making it more durable, corrosion-resistant, and aesthetically appealing. It involves immersing aluminum parts in an electrolyte bath and passing an electric current through them. This results in the formation of an oxide layer on the aluminum’s surface, known as an anodic oxide coating.
Benefits of Anodizing
- Durability & Wear Resistance: the anodic oxide layer significantly improves the hardness and wear resistance of aluminum with type III hardcoat anodizing, making it suitable for critical wear applications
- Corrosion Resistance: anodized surfaces are highly resistant to corrosion, even when exposed to harsh chemicals or outdoor elements, which ensures the longevity of your components in challenging environments
- Aesthetic Appeal: anodizing offers a range of color options including black and clear, making it possible to achieve the desired appearance
- Electrical Insulation: anodized aluminum serves as an effective electrical insulator, preventing electrical conductivity that might be problematic in certain applications
- Environmentally Friendly: anodizing is an environmentally friendly process, producing minimal waste and emissions compared to alternative surface treatments
