WN2
metal· WN2
WN2 is a tungsten-based refractory metal alloy, likely a tungsten-nickel or tungsten-nickel-iron composite designed for high-temperature and high-strength applications. This material is valued in aerospace, defense, and industrial heating applications where exceptional hardness, thermal stability, and resistance to wear are required at elevated temperatures.

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.
