When components are engineered to perform in the harshest conditions—salt-rich air, high humidity, rapid temperature swings, and constant mechanical stress—corrosion protection isn’t optional. It’s mission-critical.
Black Zinc-Nickel plating has quickly become one of the premier finishing choices for aerospace, defense, automotive, and industrial applications. At Aerospace Metals LLC, we provide high-performance Black Zinc-Nickel coatings engineered for reliability, durability, and clean, modern aesthetics.
What Is Black Zinc-Nickel Plating?
Black Zinc-Nickel is an alloy electroplating finish consisting of:
- Zinc + 8–15% Nickel
- Followed by a black trivalent passivation
- Optionally sealed for enhanced corrosion resistance
The result is a sleek black finish that delivers exceptional corrosion resistance without sacrificing electrical conductivity or dimensional precision.
Why Black Zinc-Nickel Is Becoming the Industry Standard
1. Exceptional Corrosion Resistance
Black Zinc-Nickel outperforms traditional zinc and zinc-iron finishes by a wide margin—often exceeding 1,000+ hours of salt spray resistance with proper sealing. This makes it ideal for:
- Aerospace assemblies
- Military hardware
- Outdoor industrial equipment
- High-moisture applications
2. Environmentally Friendly & RoHS Compliant
Modern trivalent black passivates are free of hexavalent chromium, making them:
- More environmentally sustainable
- Globally compliant
- Safer for operators and end-users
3. Uniform Appearance with a Modern, Tactical Look
The deep black, low-gloss finish isn’t just functional—it’s visually striking. Industries choose Black Zinc-Nickel when they need:
- A high-end, tactical aesthetic
- Consistent color across batches
- A durable coating that doesn’t fade easily
4. Superior Wear Resistance
Nickel increases coating hardness and reduces friction, providing:
- Better protection against abrasion
- Longer component lifespan
- Fewer field replacements and lower maintenance costs
5. Dimensional Stability
Black Zinc-Nickel applies with precision and minimal buildup. This makes it ideal for:
- Tight-tolerance aerospace components
- Fasteners and fittings
- Hydraulic and pneumatic parts
- Electrical housings
Common Applications in Aerospace & Defense
At Aerospace Metals, Black Zinc-Nickel is frequently used on:
- Brackets & housings
- Structural hardware
- Fasteners
- Connectors & couplings
- Actuation components
- Landing gear subcomponents
