Electroless Nickel Plating (ENP)

Plating without electricity: dead-uniform thickness everywhere, bores and threads included.

Process specifications

Parameter	Value
Process group	Plating
Coating thickness	8–50 µm
Tolerance impact	Deposits uniformly within ±10% of nominal thickness across any geometry — deep bores and threads receive the same coat as outer faces. We machine compensated dimensions and reliably land final size even on IT7 / ±0.01 mm features.
Corrosion rating	500–1,000 h salt spray (high-phosphorus grades, ASTM B733).
Appearance	Uniform satin silver, slightly warmer than electrolytic nickel; follows the underlying texture.

⚠ Not suitable for

Extreme-abrasion or very thick builds above ~75 µm (hard chrome keeps the edge there); surfaces later welded (nickel-phosphorus contaminates welds); zinc die castings and magnesium without special pretreatment; budgets where commodity zinc is sufficient.
