· W3 N4

W3 N4 is a tungsten-nickel composite or alloy system, likely a tungsten-based material with nickel as a secondary phase or binder component. This material family is typically developed for high-temperature, high-density, or wear-resistant applications where tungsten's extreme hardness and density combine with nickel's toughness and ductility to create a balanced engineering solution.

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.
