· WAlN3

WAlN3 is a ternary nitride compound combining tungsten, aluminum, and nitrogen, belonging to the family of refractory metal nitrides and hard ceramic materials. This material is primarily of research and developmental interest rather than an established industrial commodity; it is investigated for potential applications in extreme-environment coatings and hard surface technologies due to the high hardness, thermal stability, and oxidation resistance characteristic of tungsten-based nitrides. WAlN3 represents an emerging material platform where engineers explore compositional tuning of the W-Al-N system to balance hardness, toughness, and thermal properties for next-generation cutting tools, wear protection, and high-temperature structural coatings.

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.
