· WN

WN is a tungsten-nickel alloy, a dense refractory metal composite that combines tungsten's high melting point and stiffness with nickel's toughness and workability. It is widely used in high-temperature structural applications, radiation shielding, and kinetic energy projectiles where extreme density and thermal stability are critical, particularly in aerospace, defense, and nuclear industries where conventional steels cannot withstand sustained elevated temperatures or intense mechanical loads.

Regulatory Screening

Environmental

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.
