BeIrW
metal· JVASP-70340· BeIrW
BeIrW is a ternary metal alloy combining beryllium, iridium, and tungsten—a rare composition designed to achieve extreme hardness and high-temperature stability through the combination of refractory metals (iridium and tungsten) with lightweight beryllium. This material appears to be primarily in experimental or specialized research development rather than established industrial production, targeting niche applications where exceptional density, hardness, and thermal resistance converge with minimal weight constraints.

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.
