Electro-less Nickel plating differs from electroplated nickel in that the deposition is autocatalytic. This means that the nickel is deposited on a substrate material without the use of an external electrical current. Many of the properties of Electro-less Nickel plating are superior to those achieved by electroplating.


Corrosion and chemical resistance are better, ductility is improved, the deposit is harder (especially after heat treating), and the magnetic properties are different. One of the important features of Electro-less Nickel plating is the ability to obtain deposits of uniform thickness even on confined inside surfaces.
