LOWNIP® - LOW-PHOSPHORUS ELECTROLESS NICKEL PLATING
HIGH HARDNESS, EXCELLENT WEAR RESISTANCE, GOOD THERMAL AND ELECTRICAL CONDUCTIVITY
- Phosphorus content below 4%
- High-density microcrystalline structure
- High hardness (~700 HV100, up to 1100 HV100 after heat treatment)
- Excellent resistance to abrasive and mechanical wear
- Good electrical and thermal conductivity
- High stability in alkaline environments (caustic alkalis)
- Suitable for small parts and large-scale components
- Uniform deposition even on complex geometries
LowNiP® is a low-phosphorus (2-4%) electroless nickel plating, characterized by a predominantly crystalline structure (β-phase) with very fine grains.
This microstructure provides the coating with high surface hardness and excellent wear resistance, making it ideal for components subjected to friction or severe mechanical stresses, such as gears, valves, molds, and flanges.
Compared to high-phosphorus electroless nickel coatings, LowNiP® offers higher electrical and thermal conductivity, making it suitable for electronic and engineering components as well.
Corrosion resistance is lower in acidic or oxidizing environments, but excellent in alkaline conditions, where other coatings may show performance limitations.
