Advanced Specs & Options

Hardcoat Compliance & Grading

We strictly execute Type III hard anodizing to meet aerospace and defense specifications, producing a dense, non-conductive oxide layer that provides the ultimate structural protection for UAV aluminum components.

Micro-Hardness Engineering

Our process achieves surface hardness levels between 60 and 70 Rockwell C, effectively transforming the aluminum surface into a wear-resistant barrier capable of withstanding high-speed impact and abrasive debris.

Ultra-Precise Layer Control

We monitor oxide build-up with micron-level precision, specifically calibrating for the 50% penetration and 50% surface growth rule to ensure that critical bearing seats and motor mounts maintain a perfect interference fit.

Specialized Material Treatment

For moving assemblies and friction-sensitive parts, we offer post-anodizing PTFE (Teflon) impregnation, further reducing the coefficient of friction while maximizing the corrosion resistance of the hardcoat.

Process Control & Quality Assurance

Precision Pre-treatment

Ultrasonic cleaning to ensure a contaminant-free surface for dense oxide growth.
Low-Temp Hard Anodizing

Stable parameters and cooling to achieve maximum surface hardness and density.
Functional Sealing

Optional sealing to maximize corrosion resistance or enhance PTFE-impregnation.
Metrological Verification

Precise thickness and bore checks to ensure assembly within ±5μm tolerances.

Frequently Asked Questions

How do you manage the dimensional growth on tight-tolerance bores?

We calculate the 50% surface buildup caused by hard anodizing to ensure your precision bearing seats and threaded holes remain within your specified engineering limits.

What specific hardness levels can your process achieve?

Our low-temperature baths produce a dense oxide layer typically reaching 60–70 Rockwell C, providing the extreme abrasion resistance required for high-friction drone components.

Can you provide selective masking for electrical grounding points?

Yes, we use high-precision masking techniques to keep specific contact areas raw, allowing for perfect conductivity while the rest of the frame receives the hard anodizing treatment.

How does your process impact the fatigue life of the aluminum?

We optimize our chemical concentration and current density during hard anodizing to minimize surface micro-cracking, preserving the structural integrity of parts under high flight loads.

Is it possible to achieve color consistency with Type III coatings?

While thicker coatings naturally appear darker, we utilize calibrated dye cycles and digital spectrophotometers to maintain uniform color matching across your entire production batch.
