Unlike conventional electroplating, no electrical current is required for deposition. The electroless bath provides a deposit that follows all contours of the substrate exactly, without building up at the edges an corners. A sharp edge receives the same thickness of deposit as does a blind hole.

The most widely used engineering form of electroless plating is, by far, electroless nickel. Electroless nickel offers unique deposit properties including uniformity of deposit properties in deep recesses, bores and blind holes. Most commercial deposition is done with an acid phosphorus bath owing to its unique physical characteristics, including excellent corrosion, wear and abrasion resistance, ductility, lubricity, solderability, electrical properties and high hardness.
NBP offers different types of Electroless Nickel

Low Phos - A hard deposit approaching hard chrome with no heat treatment necessary for hardness. Comparable to boron electroless nickel. This deposit is used mainly for its hardness and wear properties.

Mid Phos – By far the most widely used deposit. It has a Bright uniform appearance and is used for both decorative and electronic applications.

High Phos - Compressively stressed deposits with excellent adhesion, ductility, and superior corrosion resistance.
