Electronic, medical, automotive, aerospace, and defense industries all use electroless nickel-PTFE when components require more lubricity than traditional plating surfaces. They call for hard, uniform, self-lubricating coatings like electroless nickel-PTFE (EN-PTFE).

EN-PTFE is hard, and ideal for sliding and wear applications. It is also dry lubricating, highly lubricious, non-wetting, and has excellent wear and corrosion resistance. EN-PTFE is a low friction wear plating. It is ideal in applications where conventional lubricants cannot be used, such as injection molds, stamped washers and non-galling threaded parts. It is also now used as a more environmentally friendly alternative to cadmium-plated connectors.
Teflon Particles Co-Deposited in Electroless Nickel Increase Lubricity

Extreme self-lubrication (due to PTFE)
Superior wear, corrosion and friction resistance
Dry lubrication
Low coefficient of friction (vital for sliding, moving & friction-wear applications)
Enhanced release, non-stick surface (for molding operations)
Uniform coating and deposit thickness (even on complex geometries)
Non-wetting surface repels water, oil, and other potential contaminants (due to PTFE)
Hardness:
250 – 300 HK100 (as plated)
375 – 425 HK100 (heat treated, 350°C/2 hrs)
Phosphorus Composition: 7-10% by weight
PTFE (Teflon®) Composition: 4-9% by weight (13%-27% by vol.)
Typical coating thickness of .0001″ – .0005″ thick
Coefficient of Friction: Less than 0.10
End-Of-Life Vehicle (ELV) Regulations and Restriction of Certain Hazardous Substances (RoHS) compliant
Conforms to SAE 2454 specifications
Ideal in low loading and low temperature applications
Repels water, oil, and other potential contaminants (due to PTFE)

EN-PTFE can be further enhanced, by also coating opposing surfaces with EN-PTFE.
