What Is Anodizing?

Anodizing is an electrochemical process that converts the surface of aluminum into a durable, integral oxide layer. Rather than sitting on top of the metal like paint or plating, the anodic coating grows out of the aluminum itself, so it cannot chip or peel the way an applied film can.

The part is submerged in an electrolyte - at DMF, a sulfuric acid bath - and an electric current drives the controlled growth of aluminum oxide. The result is a harder, more corrosion-resistant surface that can also be dyed for color or sealed for added protection. Because the coating is grown into the substrate, anodizing preserves dimensional predictability while dramatically improving surface performance.

What Are the Benefits of Anodizing?

Anodizing gives aluminum parts a combination of durability, protection, and finish quality that few other processes can match at a comparable cost. For Austin engineers weighing surface treatments, the anodic layer delivers advantages across mechanical, electrical, and cosmetic requirements.

• Superior corrosion resistance from an oxide layer grown into the aluminum surface
• Increased surface hardness and wear resistance, especially with Type III hardcoat
• An electrically insulating finish for both Type II and Type III coatings
• Durable color options that will not chip or peel like applied coatings
• Improved adhesion base for post-anodize laser engraving, screen printing, or powder coating
• A predictable, uniform finish suitable for prototype through production volumes

Type II vs. Type III Anodizing Capabilities

DMF runs both common anodizing types in-house, each compliant with MIL-A-8625 and each using a sulfuric acid electrolyte. Choosing between them comes down to how much wear resistance, coating thickness, and hardness your Austin application requires.

Type II Anodizing

Type II is the standard decorative and protective anodize, producing a coating typically 0.0003" to 0.0006" thick (roughly 8-16 micrometers). It is well suited to parts that need corrosion protection, an insulating surface, and color without a heavy build. Available colors include clear, black, green, red, and orange, with additional colors possible given adequate volume.

Type III Hardcoat Anodizing

Type III, or hardcoat anodizing, builds a denser, thicker coating - typically 0.001" to 0.0025" - with surface hardness up to 60-70 on the Rockwell C scale for demanding wear applications. To achieve this, we use a dedicated chiller to hold optimal bath temperature and digitally controlled power rectifiers for granular process control. Type III PTFE impregnation is also available to add a non-stick surface and lubricity for mating parts.

Masking, Colors, and Tolerances

Custom selective masking is available to protect threads, mating surfaces, and other critical-fit features from coating. Because anodizing grows both into and out of the surface, you should account for coating growth on tight-tolerance fits, and our team will help plan for it. Parts must fit within our tank capacity of up to 84" long by 42" high by 18" deep.

The Anodizing Process

Every Austin order follows a controlled sequence at our Houston facility, engineered for repeatable, specification-compliant results.

1. Intake and Inspection. We receive your aluminum parts, review the specification, CAD files, and any masking or handling requests, and confirm that geometry fits within our tank capacity.

2. Surface Preparation. Parts are thoroughly cleaned, and bead blasting is applied upon request to achieve a uniform pre-anodize texture and remove surface contamination.

3. Masking and Racking. Custom selective masking protects threads and critical-fit surfaces, and parts are racked to control contact points, with rack marks and special handling accommodated per your requirements.

4. Anodizing. Parts are anodized in the sulfuric acid electrolyte to the specified Type II or Type III build, with Type III run under chiller-controlled temperature and digitally controlled rectifiers.

5. Color, Seal, and Final Inspection. We apply the specified color, seal the coating, add optional Type III PTFE impregnation when requested, then inspect against specification and prepare your order to ship back to Austin.

Aluminum Alloys We Anodize

Anodizing is an aluminum-specific process, and alloy chemistry directly affects coating appearance and performance. DMF anodizes the four major wrought aluminum families in both Type II and Type III, so your Austin parts are matched to the right process for their alloy.

2000 Series: High-strength copper-alloyed aluminum common in aerospace and structural components; anodized to add corrosion protection to demanding parts.

5000 Series: Magnesium-alloyed aluminum valued for corrosion resistance and weldability, well suited to marine and general-purpose anodizing.

6000 Series: Versatile magnesium-silicon alloys such as 6061 that anodize cleanly and are widely used across electronics, transportation, and industrial hardware.

7000 Series: High-strength zinc-alloyed aluminum used in aerospace and performance applications where wear and fatigue resistance matter most.
