Black Oxide Coating
Black Oxide Coating Services
Strength Meets Style — All in One Surface
Need corrosion resistance without changing dimensions? Want a deep, professional black finish that doesn’t flake or peel? Black Oxide is the solution. At Fiesco, we provide industrial-grade black oxide finishing that protects, enhances, and adds value—without altering the integrity of your parts.
This chemical conversion coating is ideal for machined components, fasteners, tools, gears, and firearms, offering a sleek black look with added functionality.
What Is Black Oxide?
This finish is more than just good looks—it delivers:
✅ Minimal dimensional change (just 5–10 millionths of an inch)
✅ Mild corrosion resistance (enhanced with oil or wax sealants)
✅ Reduced light reflection and glare
✅ Improved lubricity and wear resistance
✅ Cost-effective alternative to plating or painting
Perfect for aesthetic value, light corrosion protection, and precision components.
