Substrate

ENP has the ability to nickel plate many base materials. Along with its huge plating line normally used for plating ferrous metals, ENP has another line dedicated to plating aluminum.

Nickel Plating can be applied to a multitude of base metals including:

Aluminum

Heat Treated Steel

Ceramics

Copper

Nickel Alloys

Zinc Die Casts

Copper Alloys

Steel

Sintered Metals

Brass

Stainless Steel

Plastics

Bronze

Tool Steels

Titanium

Substrate material can greatly influence the nickel deposit properties.

Adhesion

Excellent adhesion of electroless nickel deposits can be achieved on a wide range of substrates, including steel, aluminum, copper and copper alloys. Typical bond strengths reported for electroless nickel on iron and copper alloys range from 50 to 64 kpsi (345 to 441 M Pa). The bond strength on light metals, such as aluminum, tends to be lower, in the range of 15 to 35 kpsi (103 to 241 M Pa) for most alloys.

Heat Treatment

Heat treatment is commonly employed to improve adhesion of EN on all metals, particularly on light metals such as aluminum or titanium. During this heat treatment diffusion occurs between the atoms of the coating and the substrate.

Brightness

The brightness and reflectivity of electroless nickel depends on the surface finish of the substrate. In other words, electroless nickel reproduces the finish to which it is applied and is not a filler coating such as chrome.
