ErW3
metal· JVASP-127639· ErW3
ErW3 is a tungsten-based intermetallic compound containing erbium, belonging to the rare-earth refractory metal family. This material is primarily of research interest for high-temperature applications where exceptional hardness and thermal stability are required, though industrial adoption remains limited compared to conventional tungsten alloys. Its rare-earth erbium addition provides potential benefits in creep resistance and oxidation protection at extreme temperatures, making it notable in advanced aerospace and nuclear materials development.

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.
