Surface Finishing

Nickel Plating Services

Nickel deposits improve corrosion resistance, hardness, and solderability — electroless nickel (EN) plates uniformly even in holes and recesses, making it ideal for precision mechanical and electronic components.

Process Overview

Electroless Nickel

Mid-phosphorus EN typically 25–50 μm. Uniform thickness on complex geometry without edge buildup.

Hardness & Wear

Heat-treated EN reaches 48–50 HRC — suitable for tooling, shafts, and wear surfaces.

Underplate Stack

Copper or bright nickel underplates for multi-layer systems per your spec or industry standard.

Frequently Asked Questions

Electroless vs electrolytic nickel?

Electroless deposits uniformly in holes and on complex shapes. Electrolytic nickel is economical for decorative bright finishes on visible exterior surfaces.

Does plating affect tolerances?

Yes — specify plating thickness and we machine undersize accordingly. EN is predictable and often ±10% of nominal thickness.

Can you plate internal threads?

Electroless nickel plates threads uniformly. We still recommend masking if class-fit threads must be preserved.
