Electroless Nickel (EN) plating, is an auto-catalytic or chemical plating process,
has been used across a myriad of industries since the 1950s for its exceptional
wear and corrosion capabilities.
Uniform Thickness. Being an auto-catalytic process, EN does
not rely on the anode/cathode relationship as in electrolytic plating processes
- resulting in uniform coating thickness across the surface of the part(s), regardless
of shape and size.
Accuracy and Consistency. The final coating thickness
of EN is determined based on the length of time the part(s) are submerged in the
plating bath. Through careful and meticulous bath maintenance, the final coating
thickness can be maintained within .00005”±, typical applications only require .0001”
±.
High Phosphorus EN. High Phos Electroless Nickel,
ENHP, provides superior corrosion resistance capabilities compared to other formulation
of EN. ENHP can be heat treated after plating to improve the hardness and adhesion
of the final coating.
Medium Phosphorus EN. Medium Phosphorus EN, MidPhos
EN, is the most readily available type of EN. Provides both corrosion resistance
and wear capabilities. MidPhos EN deposits slightly faster than ENHP, resulting
in a semibright final coating.
Low Phosphorus EN. Low Phosphorus EN, LowPhos EN,
is the hardest of the EN formulations. Provides excellent corrosion resistance in
alkaline environments. Final deposit is bright in appearance.
RoHS Compliance. Twin City Plating provides a number
of different RoHS Compliant EN formulations. For specific information please contact
us.
Composites. EN Composite coatings are creating many
new opportunities where traditional EN formulations did not fully satisfy customer/industry
requirements. Wear-ability, hardness, lubricity – depending on the formulation there
may be a Composite EN coating that makes the difference for your application. Call
for more details.
