Few industries have stricter performance and compliance requirements than aerospace. Every part, whether structural, mechanical, or electronic, must function in demanding environments where failure is not an option. Aircraft components face extremes of temperature, vibration, and atmospheric pressure, as well as constant exposure to corrosive conditions. Proper metal finishing is essential to ensuring these parts perform reliably, meet regulatory requirements, and maintain safety in flight.
Metal Finishing Group provides aerospace manufacturers and suppliers with specialized finishing services designed for compliance with FAA, MIL-SPEC, and industry standards. Our processes deliver corrosion resistance, wear protection, and electrical conductivity where needed, ensuring every component contributes to safe and efficient aircraft operation.
Industry-Specific Applications
Aerospace hardware spans a wide range of materials and functions, and each benefits from specialized finishes.
Structural Components
Landing gear, fasteners, and aluminum structures are commonly treated with anodizing to provide enhanced corrosion resistance and wear protection. Hardcoat anodizing is applied where additional hardness and durability are required.
Aircraft Hardware and Fasteners
Cadmium plating remains a critical coating for aerospace fasteners, providing sacrificial protection against corrosion in both marine and atmospheric conditions. This process is widely used on bolts, nuts, and fittings where strength and reliability are essential.
Avionics and Electrical Systems
Connectors and circuit components rely on gold and silver plating for conductivity and resistance to oxidation. Electroless nickel provides a uniform, protective coating on complex electronic assemblies.
Engine and Power Systems
Electroless nickel and sulfamate nickel coatings help protect high-performance engine components exposed to heat and friction. These finishes extend part life and improve wear resistance.
Cabin and Interior Hardware
Decorative chrome and bright nickel are used on interior fixtures and passenger hardware, combining aesthetic appeal with corrosion resistance and long-term durability.
Together, these finishes ensure aircraft hardware and systems meet the dual demands of safety and reliability in flight.
Capabilities and Processes for Aerospace Finishing
Metal Finishing Group offers a comprehensive line of services tailored to aerospace requirements.
- Anodizing (Type II and Type III Hardcoat) – Applied to aluminum for corrosion resistance, wear protection, and increased surface hardness.
- Cadmium Plating (Clear and Yellow) – Provides sacrificial corrosion resistance and excellent lubricity, widely used on aerospace fasteners.
- Electroless Nickel (Mid-Phos, High-Phos) – Delivers uniform coatings on complex parts, ideal for engine and electronic components.
- Sulfamate Nickel – Provides low-stress, ductile coatings suitable for critical aerospace applications.
- Gold Plating – Ensures high conductivity and oxidation resistance for avionics and connectors.
- Silver Plating – Applied to RF connectors and electrical systems requiring high conductivity.
- Bright Nickel and Decorative Chrome – Combine corrosion resistance with aesthetic value in interior applications.
- Passivation – Enhances stainless steel corrosion resistance, ensuring parts meet aerospace cleanliness standards.
Each service is supported by masking, plugging, bead blasting, and polishing, ensuring that aerospace parts are finished to the most precise requirements.
Compliance and Performance Standards
Aerospace components must meet strict compliance regulations. Metal Finishing Group’s processes align with:
- MIL-A-8625 for anodic coatings on aluminum
