Product Detail

When your automated production line, robot housing, or custom machinery requires a product that surpasses standard silver profiles, choose our Black Anodized 40 Series Industrial Aluminum Profiles. This is far more than just an aesthetically pleasing addition; it's a precision-designed structural component that perfectly blends the inherent strength of 6063-T5 aluminum alloy with a deep, uniform black anodized finish. The resulting frame boasts a remarkably clean appearance in customer-facing equipment, effectively resists oil stains and fingerprints, and withstands the harshness of corrosive workshop environments, ensuring durability.

Why choose black anodizing instead of transparent or original color surface treatment?

Many engineers default to using natural or clear anodized profiles because they are readily available. But consider the actual advantages of black anodized 40 series profiles:

Conceal wear and tear

On high-traffic assembly lines, black surfaces can cover scratches, dust, and grease stains, keeping equipment clean without frequent wiping.

Reduced light reflection

Ideal for optical inspection stations, laser housings, or any environment where stray reflections can interfere with the sensor or operator’s line of sight.

Enhanced corrosion resistance

The anodizing process thickens the natural oxide layer. Black profiles perform well in humid or mildly chemical environments.

Our process ensures an oxide film thickness of at least 10-15 micrometers, resulting in a deep, uniform black surface that will not fade even under typical indoor industrial lighting or UV exposure.

"40 Series" refers to a nominal width of 40 mm for the main face of the profile. We offer a variety of cross-sectional shapes to meet your structural and weight requirements: the 4040 light-duty profile is suitable for light-duty housings, chassis, and 3D printer frames; the 4040 heavy-duty profile has increased wall thickness and is suitable for load-bearing columns, workbenches, and AGV frames; the 4080 profile is suitable for machine tool bases, conveyor rails, and gantry beams.

The black anodizing process is performed after precision cutting and before any secondary processing (if necessary). The main advantages of this process are:

Hardness

The hardness of the anodized layer effectively protects the underlying soft aluminum from scratches.

Insulating surface

Provides electrical insulation (if grounding is required, the anodized layer can be etched off at the contact point).

Easy to clean

Oil stains, coolant, and dust can be easily wiped away without leaving stains on the surface.

We do not use any organic dyes that will fade. Instead, we use electrolytic coloring (a two-step anodizing process) to achieve a deep metallic black and ensure consistent color across batches—crucial for repeat orders of the same project.

Each project has unique dimensional requirements. We offer custom-length black anodized 40 series profiles to avoid waste and extra cutting work:

📏 Cutting

Lengths range from 50 mm to 6,000 mm.

📐 End milling

Right-angle or custom angles (45°, 30°, etc.) for miter joints.

🔘 Drilling

Through holes, countersunk holes for direct bolt connections.

🔩 Tapping

Threaded holes at ends or sides, eliminating exposed T-nuts.

We operate as a manufacturing partner, not a warehouse of inventory. Each order is custom-made to your specific requirements, ensuring zero inventory backlog. You simply provide a cutting list, and we deliver ready-to-assemble components—no additional processing time required.

Practical Applications of Black 40 Series

Automated Robot Workstation Features a 40x80 column with a black anodized finish and a transparent polycarbonate panel. The dark frame minimizes visual distractions, helping operators focus on the robot's work area. The black surface also conceals scratches from the teach pendant cable.

Electronic assembly cleanroom workstations In electrostatically sensitive environments, black anodized profiles offer significant advantages—they reflect less light compared to bright silver, reducing eye strain under the strong light of a cleanroom. The smooth, non-porous surface does not easily accumulate particulate matter and is easy to clean and disinfect.

Professional CNC machine tool frame Amateur enthusiasts building their own CNC engraving machines or milling machines, as well as those in small workshops, often choose black 40-series profiles to create a high-end look. The rigidity of the 40x80 profiles effectively reduces vibration, while the black anodized finish gives the machine a professional, factory-grade appearance.

Why choose us as your partner?

Technical Support: We offer inter-engineer technical support—our team is proficient in CAD software. Please send us your drawings or cutting lists, and we will recommend the most cost-effective profile selection and processing solutions.

In-Stock Dies: For standard 40 series profiles, we have extrusion dies in stock. Custom lengths and machining are available at the cost of the actual machining steps.

Lead Time: Since we do not keep pre-cut profiles in stock, your order will go directly into our production queue. The typical lead time for custom-cut black anodized profiles is 15-20 working days.

Consistency: We have reserved dedicated production slots for the black anodizing process to ensure that replenishment products several months later will perfectly match your original chassis.
