Zinc Plating for Aerospace Components
Aerospace-grade zinc coating adds a tough, corrosion-resistant layer that improves durability, appearance, and protects delicate structures from harsh environments.
Aerospace-grade zinc coating adds a tough, corrosion-resistant layer that improves durability, appearance, and protects delicate structures from harsh environments.
Zinc plating applies a uniform metallic layer to aerospace parts, preventing oxidation, extending service life, and enhancing aesthetics. Every one of our projects is managed to AS9100D requirements with complete traceability and ITAR compliance.
The coating thickness, ranging from ±0.005 mm to ±0.01 mm, is carefully controlled, ensuring that aerospace components maintain precise tolerances and reliable performance even under extreme conditions.
Acts as a sacrificial shield, preventing base-metal corrosion and increasing long-term reliability.
Reduces abrasion and surface damage, maintaining function in demanding aerospace environments.
Consistent thickness between 0.005 mm and 0.015 mm ensures compliance with AS9100D tolerances.
Produces a smooth, bright surface that improves aesthetics and traceability documentation.
Offers a durable protective finish without adding unnecessary weight or expense.
Every part is inspected using CMM, microscopes, and 2.5D equipment to maintain quality and traceability.

Precision Tolerance Preservation| Finish / Type | Purpose | Thickness | Corrosion | Color / Appearance | Notes |
|---|---|---|---|---|---|
| Clear/Blue Zinc (Trivalent) | General indoor hardware & electronics | 5 – 12 μm | Moderate (24 – 72h) | Bright Silver-Blue | Most common & economical; Industry standard for small screws. |
| Yellow Zinc (Thick Film) | Automotive underbody & construction | 8 – 15 μm | High (96 – 168h+) | Iridescent Yellow/Gold | “Self-healing” properties on scratches; thicker passivation layer. |
| Zinc-Nickel Alloy (High Perf.) | Extreme environment & high heat | 10 – 15 μm | Extreme (500 – 1000h+) | Gunmetal / Silver / Black | Hardest zinc finish; 5x protection of std zinc; Best for Aerospace. |
| Black Zinc | Decorative & tactical (non-reflective) | 5 – 12 μm | Moderate (Variable**) | Matte or Gloss Black | Cosmetic focus; shows scratches easily; often includes a topcoat sealer. |
