How Anodization is Used to Create Coyote Brown Camouflage Coatings

Known as hard coat anodizing or Type III anodizing, hard anodization is a specialized treatment process that creates a coating on the surface of aluminum to augment the metal’s material properties. This process forms a comparatively thick coating of aluminum oxide on the metal’s surface, up to about 25 microns ( 0.001 inch) in thickness. The coating achieved through hard anodizing develops due to an electrochemical reaction that causes en oxide layer to form on aluminum surfaces.

Hard anodization is used for many defense-related applications, partly due to its ability to produce military camouflage that works well for terrain in many types of desert. The Coyote Brown color falls under the Mil-A-8625 military specification. Besides its use as desert camouflage, hard anodization also improves the performance of aluminum-based gear used by the military in difficult tactical conditions.  

Hard Anodizing & Coyote Brown 

Type III or hard anodizing uses lower temperatures for the electrolytes, which are kept in refrigerated tanks, to produce denser currents that then result in a thicker oxide layer. Items anodized through this process show better corrosion and wear resistance than conventional anodizing techniques, due in part to the thicker coating produced. Many defense contractors are required to use X-ray machines to certify the thickness of the coating so that the military camouflage pattern and surface treatment conform with military specifications.  

Hard adonizing also allows aluminum surfaces to better retain colored dyes, making the process integral for producing certain types of desert, woodland and other military camouflage. This capability has proven useful for coloring exterior gun components and other aluminum-based surfaces of military kit. Hard anodized coatings are also used in frames, handguards, receivers and other components used by the US military.

In the early 2000s, the US Marine Corps began to use a color known as coyote brown as part of its military camouflage. The camouflage used by the US military today includes this brownish shade, which originated from a paint color originally produced by Ralph Lauren Home, which discontinued the color that the company referred to as “coyote.” Brown camouflage of this tone helps soldiers and equipment blend into their surroundings, especially in wooded and desert areas. The level of concealment this military camouflage offers in such environments in turn makes tactical military units more effective.

Benefits of Hard Anodizing & Coyote Brown 

Coyote brown Anodize provides effective concealment in numerous types of woodland and desert terrains, enabling ground units to better blend into their surroundings. Besides the benefits of coloration, hard anodization of aluminum and its alloys in the defense sector also proves advantageous due to the metal’s lower density, along with its noncombustible and nontoxic traits. Aluminum is also malleable and highly conductive, yet without the magnetism found in steel and other iron-based alloys. Hard anodizing improves corrosion resistance, durability, performance, and wear resistance of aluminum-based military apparatus.

Better Corrosion Resistance

The thicker layer of aluminum oxide that hard anodizing creates makes the metal more resistant to corrosion. Over the past couple decades, US military hardware has additionally needed to withstand conditions found in a desert. Camouflage is only one aspect of this, as hard anodizing ensures components will be more reliable and resilient in the unyielding conditions found on 21st century battlefields, regardless of the climate and conditions.

Improved Durability 

Military gear requires resilience. While untreated aluminum offers considerable durability when exposed to harsh conditions, the metal proves even tougher when hard anodized to become coyote brown. Camouflaged surfaces become three times as strong as aluminum in its natural state. Unlike paint, this coloration doesn’t chip, flake, or peel, making it an especially long-lasting military camouflage. The anodized layer helps military kits survive frequent use and heavy loads, whether used in forests or deserts. Camouflaged items that are colored coyote brown generally have longer service lives.

Augmented Performance

For military applications, the performance of soldiers’ gear is often critical to successful missions. Hard anodizing equipment to generate coyote brown camouflage not only conceals but also reduces friction, augmenting wear resistance while helping maintain an item’s dimensional stability. Even when exposed to extreme conditions, hard anodization ensures the reliability of items colored the shade of coyote brown. Camouflaged patterns double as tough finishes for military equipment, ensuring it functions effectively in the harsh conditions found on the battlefield.   

Resisting Wear

While hard anodized surfaces are stronger, their wear resistance is ten times that of conventionally anodized aluminum. When used for desert camouflage, the thick aluminum oxide layer enables surfaces to withstand abrasive windstorms, high temperatures or other conditions found in the desert. Military camouflage also retains other colors better when hard adonized, not just coyote brown. Camouflage that resists wear also ensures that these natural colors found in their surroundings help military units avoid detection longer in the field.

How the Hard Anodization Process Creates Desert Camouflage

While anodizing surfaces increase corrosion resistance and durability, they also provide the aesthetic properties that make it work well as desert camouflage. For tactical operations in the desert, camouflage provides a means to blend into an environment where there’s often a scarcity of cover. Unlike military camouflage for wooded areas, desert camouflage helps keep weapons, vehicles, and other military equipment hidden in plain sight against a background that often matches or melds with the color coyote brown. Camouflage made via the hard anodization process additionally creates colors with low reflectivity, making equipment or soldiers even harder to spot. While enhancing durability, coyote brown desert camouflage coatings need to go through several specific steps. These include preparing the surface, electrochemically anodizing the item, dyeing the colors onto its surface, and sealing this substrate.  

There are significant benefits of military gear colored with a coyote brown camouflage pattern. Not only does it act as desert camouflage to make detection difficult in drier environments, but it also helps military kit resist corrosion, along with scratching and other wear. This non-reflective coyote brown camouflage finish ensures items aren’t readily visible in tactical situations, while its heat resistance makes it ideal for applications in the desert. Hard anodized surfaces also serve as a base layer for other types of military camouflage.
