Aluminum Hard Coating Anodizing Services
Hard coat anodizing is a proven electrochemical process that transforms a plain metal surface into an engaging exterior that provides both advanced corrosion-resistance and durability. The key difference between aluminum hard coating and standard anodization is that the process provides the surface with greater wear resistance and a smoother and harder finish. The aluminum hard coating process is ideal for transforming the surfaces of aluminum and all other types of nonferrous metals. These premium materials are used by numerous industries throughout the world to manufacture thousands of consumer, commercial and industrial products.
The Aluminum Hard Coating Anodizing Process
Our custom engineered anodizing process begins by creating a uniform aluminum oxide layer that penetrates the surface of the material. The part(s) are then placed in a sulfuric acid bath at approximately 32°F, with a density of 23 to 37 amps, for anywhere from 20 minutes to two hours. The amount of time spent submerged determines the thickness of the coating.
Aluminum Anodizing Services Custom Tailored to Your Project Needs
Aluminum hard anodizing, also known as MIL-A-8625 Type III or engineered anodizing, is similar to standard anodizing in that both are controlled electrochemical processes. However, hard anodizing is commonly performed clear or with a black dyed finish, though some prefer the aluminum dyed different colors for aesthetic purposes. Arrow Cryogenics provides both color anodizing services, as well as custom services for hard coated clear anodized aluminum.
Over time aluminum naturally forms an oxidized exterior. However, our type III custom anodizing services provides a surface that is more uniform, dense, and much harder than naturally oxidized surfaces in a quick and effective process that does not require extensive waiting.
At our state-of-the-art facility in Blaine, Minnesota, Arrow Cryogenics offers aluminum hard coat color anodizing services (Type III) and clear anodized aluminum services for dyed and non-dyed parts. We also provide standard aluminum anodizing (Type II) services. Contact us or request a quote for aluminum anodizing services today.
Hard Coat Color Anodizing Services
Depending on the alloy and the coating thickness, Arrow Cryogenics color anodizing services can provide numerous color options. To provide the best color coating options, Sampling is required by Arrow Cryogenics if a color other than black is needed. For example, the color of the aluminum after being hard coat anodized depends on the alloy and the thickness of the coating. On some alloys, the color of non-dyed (MIL-A-8625 Type III Class I) aluminum after hard anodizing will change to a gray/bronze color; on others the aluminum will turn gray-black. If the aluminum is dyed (Class II), black is the most commonly used color.
Aluminum Hard Coating Sealing Services
For applications that do not require maximum abrasion or wear resistance, we also offer aluminum hard coating sealing services. If the main function of the application is for corrosion resistance, and reduced abrasion resistance is not an issue, sealing is advised on dyed pats.
Benefits of Hard Anodizing
Arrow Cryogenics hard coat aluminum anodizing services provides anodized aluminum coating that meets Military Standard Specifications MIL-A-8625 and is available in Type III Class 1 (Non-Dyed) and Class 2 (Dyed) options. Our custom anodizing services provide strength and corrosion resistance for a range of applications. Aluminum hard coating improves the overall aesthetics of the aluminum, while providing increased the strength and corrosion resistance.
Additional benefits of engineered anodizing include:
- Easier to clean and maintain
- Improved lubrication
- Resistance to peeling, flaking and chipping
- Increased abrasion resistance
- Flame resistance
- Non-contaminating (for medical instrumentation)
Aluminum Hard Coating Applications
Hard coated custom anodizing services provides low-maintenance durability and can be used for a wide range of applications. Various industries benefit from the use of anodized aluminum parts, including:
