Durable & Lightweight Anodized Finishes for Drone Parts

Customization Options

Professional grade anodizing for wear-resistant and perfectly fitted drone parts.

Extreme Durability

Toughens surfaces through anodizing to resist scratches and wear.
Corrosion Resistance

Our anodizing seals aluminum against moisture and environmental damage.
Precision Fitment

Ensures tight tolerances for complex anodizing drone assembly requirements.
Professional Finish

Delivers vibrant, UV-resistant anodizing colors that will never fade.

Our anodizing ensures UAV longevity by providing vital corrosion resistance and surface hardness for aluminum structures. Key applications include drone frames, motor mounts, landing gear, and gimbal components.

We specialize in Mil-Spec Type II and Type III hard anodizing, optimized for 6061 and 7075 aluminum alloys. Our team employs precision masking to maintain tight tolerances on bearing bores and protect electrical grounding points. Combined with bead blasting and custom color matching, we ensure durable, high-performance finishes that meet strict engineering standards.

Anodizing Specifications & Options

Anodizing Types

We execute Type II (Sulfuric) and Type III (Hardcoat) anodizing per MIL-A-8625 standards. Our process achieves coating thicknesses from 15µm to 50µm+, providing the exact surface hardness and density required for high-stress UAV environments.

Surface Roughness

We meticulously manage pre-treatments and etching times to maintain specified Ra values as low as 0.4μm. This ensures optimal aerodynamic performance and a consistent matte or glossy texture across all drone aerodynamic surfaces.

Dimensional Tolerance

To ensure critical CNC bores and threads meet final specs, we calibrate immersion times to control oxide growth within ±5μm. This precision management accounts for the 50% penetration/50% growth rule of the anodic layer, guaranteeing perfect assembly fitment.

Color Matching

Utilizing spectrophotometer testing and Delta E (ΔE) control < 1.0, we guarantee near-perfect color uniformity. Our UV-stable dyes ensure that whether it’s a batch of 10 or 1,000, your brand colors remain consistent and fade-resistant.

Process Control & Quality Assurance

Cleaning & Prep

Remove oils and residues for uniform oxide formation.
Controlled Anodizing

Stable parameters for consistent thickness and appearance.
Advanced Sealing

Improves corrosion performance and durability.
Quality Verification

Precise thickness checks to meet tight tolerances.

FAQs about Anodizing Service

How do you control dimensional growth during the process?

We calibrate our anodizing immersion times to manage the 50% surface buildup, ensuring your high-precision CNC drone components maintain their specified engineering tolerances.

Which anodizing type do you recommend for high-wear parts?

We provide Type III Hardcoat anodizing for structural components like motor mounts, creating a dense, wear-resistant layer that far exceeds the durability of standard finishes.

Can you protect specific areas from the anodizing layer?

Our team applies precision masking before anodizing to preserve raw metal on grounding points, ensuring your drone electronics maintain perfect electrical conductivity.

How do you guarantee color uniformity for large orders?

We utilize digital spectrophotometers and stabilized chemical baths during anodizing to ensure that every frame and arm matches your brand’s exact color profile perfectly.

What measures do you take to prevent part damage?

We use custom-designed racking systems during anodizing to prevent contact marks and vibration damage, ensuring that delicate, thin-walled drone parts arrive in pristine condition.

How do you verify the quality of the final oxide layer?

Every batch undergoes eddy-current thickness testing and seal integrity checks after anodizing to confirm that the protection meets aerospace-grade durability and corrosion standards.
