Electroless Nickel Plating
Electroless Nickel Plating Services
Uniform Protection. Zero Compromise.
Precision parts deserve a finish that’s even, corrosion-resistant, and dependable—especially when they feature complex shapes or tight tolerances. At Fiesco, our Electroless Nickel (EN) plating offers a superior surface treatment that ensures your components don’t just look good—they last longer, resist wear, and meet your industry’s most exacting standards.
Whether you’re in aerospace, automotive, medical, or electronics, our EN process delivers unbeatable performance, even in high-friction or high-heat applications.
What Is Electroless Nickel Plating?
Unlike traditional electroplating, electroless nickel doesn’t require electricity to coat a surface. Instead, it uses a chemical reduction process to deposit a uniform layer of nickel-phosphorus alloy on a substrate.
This chemical method provides a consistent thickness, even on internal diameters, threads, sharp edges, and complex geometries—making it a go-to solution for high-precision applications.
Key Benefits of Electroless Nickel
Fiesco’s EN plating offers a range of functional and performance advantages:
✅ Uniform thickness on all part surfaces
✅ Superior corrosion resistance, especially in harsh environments
✅ Hard, wear-resistant finish (up to 70+ Rc with heat treatment)
✅ Improved lubricity for sliding components
✅ Excellent solderability and electrical conductivity
✅ Compatible with aluminum, steel, copper, brass, and more
Where It Shines: Industry Applications
Electroless nickel is used in industries that demand reliability and protection at the microscopic level:
- Automotive – Pistons, transmission components, fuel injectors
- Aerospace – Flight instruments, actuators, housings
- Electronics – Connectors, circuit boards, contacts
- Medical Devices – Surgical tools, implants, housings
- Mold & Die – Injection molds, stamping dies, wear surfaces
From high-volume production to precision prototyping, Fiesco delivers EN finishes that withstand time, stress, and corrosion.

Our Process: Chemical Precision
Fiesco’s plating line uses a strict, multi-stage process that ensures consistent quality and maximum performance:
- Surface Preparation
Thorough cleaning and etching to remove contaminants. - Activation & Catalyst Application
Prepares the metal surface for ideal chemical bonding. - Nickel Deposition
Immersion in a heated, pH-controlled solution containing nickel salts and reducing agents. - Optional Heat Treatment
Enhances hardness and wear resistance for critical components. - Inspection & Certification
Every part is checked for thickness, adhesion, and surface quality.
We tailor the process to your desired phosphorus content—low (2–5%), medium (6–9%), or high (10–13%)—depending on whether your priority is wear resistance, corrosion protection, or solderability.
