Aerospace Metal Finishing Solutions

At Diamond Metal Finishing, we specialize in high-performance surface finishing for aerospace components that must perform flawlessly under extreme conditions. Whether in the air, on the ground, or in space, every aerospace part we finish meets strict durability, corrosion resistance, and traceability standards — without compromising on weight, tolerances, or aesthetics.

From flight hardware to electronics enclosures, our in-house finishing services help aerospace manufacturers streamline production, meet MIL-spec requirements, and shorten time-to-market.

Comprehensive Aerospace Metal Finishing

Aerospace manufacturers choose Diamond Metal Finishing because we go beyond anodizing. We integrate multiple finishing processes under one roof — reducing handling, improving quality control, and enabling faster delivery. Here’s how each Diamond Metal Finishing service supports aerospace production:

✦ Aerospace Anodizing (Type II & Type III Hardcoat)

Anodizing is critical in aerospace because it improves the corrosion resistance, hardness, and electrical insulation of aluminum parts without adding significant weight.

• Type II Anodizing is used for corrosion protection and color-coded identification. It offers a thin, protective oxide layer and supports vibrant dyeing (clear, black, red, blue, etc.).
• Type III Hardcoat Anodizing delivers a much thicker, more durable coating — ideal for components subject to wear, abrasion, or stress. Often used for actuator housings, clamps, and flight-critical mounting brackets.
• Diamond Metal Finishing’s processes conform to MIL-A-8625, and parts are racked, masked, and inspected with aerospace precision.
• PTFE-infused anodizing is also available for low-friction assemblies.

✦ Chemical Conversion Coating (Chem Film)

Chem film is essential for aerospace parts that must remain conductive or are made from alloys that don’t anodize well.

• We offer both Clear (Class 3) and Gold (Class 1) chem film options using Alodine 1200 and Iridite systems.
• These coatings provide excellent corrosion resistance while preserving conductivity — perfect for electrical contacts, bonding areas, or grounding paths.
• Common in mixed-alloy assemblies or where selective coating is needed (e.g., connectors or back shells).

✦ Aerospace Powder Coating

For external housings, structural elements, or ground-support components, powder coating provides a durable, weather-resistant finish.

• Diamond Metal Finishing supports AAMA-compliant coatings and multi-coat systems (primer + top coat).
• Architectural-grade coatings meet UV, salt spray, and chemical exposure needs.
• We also provide custom color matching for branding or part classification.

✦ Aerospace Laser Engraving

Marking is non-negotiable in aerospace — every part must be traceable. Our laser engraving services provide durable, high-contrast markings for:

• Serial numbers and part IDs
• QR codes and barcodes
• OEM logos or asset tags
• Deep engraving for wear-prone zones

Laser engraving is available on anodized aluminum, bare metal, stainless steel, and even plastics.

✦ Aerospace Screen & Digital Printing

Aerospace panels and instruments often require detailed printed labels, legends, and branding that must withstand heat, cleaning agents, and sunlight.

• Diamond Metal Finishing offers UV-stable screen printing using specialty inks rated for aerospace environments.
• We also support digital printing for multi-color logos, overlays, and operator-facing interfaces.
• Suitable for anodized, powder-coated, or bare substrates — with precise registration and controlled ink adhesion.

✦ Aerospace CNC Routing

We route aluminum, Glastic, G10, polycarbonate, and other engineering plastics for aerospace use:

• Create precise cutouts for panels, faceplates, and enclosures
• Produce prototype or production runs with tight tolerances
• Eliminate the need for third-party machining before finishing

This service is especially valuable for avionics hardware, control panels, and mounting brackets.

Aerospace Components We Commonly Finish

Our aerospace customers range from Tier 1 integrators to specialized part suppliers. Here are some of the parts we regularly finish:

• Avionics panels and aluminum bezels
• Flight control housings and overlays
• Brackets, mounts, and actuator supports
• Structural hardware and chassis parts
• Electrical enclosures and shielding plates
• Connectors and multi-metal assemblies
• Ground-support signage and control units

Each part is processed under strict internal quality protocols, with the option for FAI (First Article Inspection), dimensional reports, and compliance certification.

Aerospace Certifications and Compliance Standards

Diamond Metal Finishing finishes aerospace components to meet or exceed the following certifications and process controls:

• ISO 9001:2015 Certified — Quality Management System
• MIL-A-8625 — Anodizing (Type II & III)
• MIL-DTL-5541 — Chromate Conversion Coating
• ITAR Registered — Defense and military projects
• Traceability Support — Certificate of Conformance, test results, and serialized reporting

We also align our processes with AMS and ASTM aerospace standards when required.
