Electroless Nickel Plating vs Nickel-PTFE Composite Plating
Electroless Nickel Plating and Nickel-PTFE Composite Plating are both electroplating & electroless plating finishes; electroless nickel is the harder surface (450–1,000 HV vs 250–500 HV).
Electroless Nickel Plating
Electroplating & electroless plating · $$$ · instant quote
Electroless nickel is an autocatalytic nickel-phosphorus coating with nearly uniform thickness on complex geometry.
Nickel-PTFE Composite Plating
Electroplating & electroless plating · $$$$
Nickel-PTFE is an electroless nickel matrix with co-deposited PTFE particles for low friction and release.
When to choose which
Choose Electroless nickel
Choose Electroless nickel when hardness and corrosion barrier outweigh low friction.
- Uniform 5–75 µm buildup on complex shapes
- About 450–550 HV as plated; suitable heat treatment can approach 1000 HV
- High-phosphorus classes provide strong barrier corrosion resistance
Choose Nickel-PTFE
Choose Nickel-PTFE when lower friction is required.
- Uniform 10–25 µm low-friction coating
- PTFE exposed throughout wear renews release behavior
- Better corrosion barrier than standalone dry lubricant
What the numbers say
- Electroless nickel is the harder surface (450–1,000 HV vs 250–500 HV).
- Electroless nickel is the lower-cost option ($$$).
- Nickel-PTFE is the thinner coating (10–25 µm), so it disturbs tight fits less.
- Electroless nickel is conductive; Nickel-PTFE is semi-conductive.
Scores side by side
Each score is 0–100 against every finish in this catalog. Corrosion is derived from salt-spray test duration and surface hardness from the finish layer's Vickers hardness where a measured figure exists; a finish that leaves the base metal's own surface is not rated for hardness. Cosmetic, lubricity and cost are FabDigit's engineering assessment. Scores and typical figures are screening data, not matched side-by-side tests or service-life rankings; ASTM B117 is a controlled salt-fog method, not a field-life prediction.

Electroless nickel vs Nickel-PTFE — frequently asked
What is the difference between Electroless nickel and Nickel-PTFE?
Electroless Nickel Plating and Nickel-PTFE Composite Plating are both electroplating & electroless plating finishes; electroless nickel is the harder surface (450–1,000 HV vs 250–500 HV). Electroless nickel is the lower-cost option ($$$). Nickel-PTFE is the thinner coating (10–25 µm), so it disturbs tight fits less.
When should I use Electroless nickel instead of Nickel-PTFE?
Choose Electroless nickel when hardness and corrosion barrier outweigh low friction. Conversely: choose Nickel-PTFE when lower friction is required.
Is Electroless nickel or Nickel-PTFE cheaper?
Electroless nickel is the lower-cost finish ($$$ against $$$$ for Nickel-PTFE) among the finishes FabDigit quotes. Both are priced per part with a lot minimum; the exact figure appears on the instant quote once the part is uploaded.
