NiPW
metal· JVASP-90277· NiPW
NiPW is a nickel-phosphorus-tungsten composite or electrodeposited coating material that combines the corrosion resistance and hardness of nickel-based systems with tungsten and phosphorus reinforcement. This material family is used primarily in wear-resistant coatings, hydraulic systems, and precision components where both durability and chemical resistance are critical; it offers a middle ground between conventional nickel plating and harder but more brittle ceramic coatings. The tungsten-phosphorus alloying approach is notable for its ability to maintain toughness while achieving high surface hardness, making it preferable in applications that experience both mechanical wear and corrosive exposure.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
