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: 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
Mission-critical assemblies

If it needs high corrosion resistance and must look great while doing its job, Black Zinc-Nickel is often the answer.
