Y3B7W
metal· JVASP-22016· Y3B7W
Y3B7W is a metal alloy containing yttrium and boron with tungsten additions, belonging to a family of high-performance refractory and superalloy compositions designed for extreme-temperature and wear-resistant applications. This material is notable in aerospace, energy, and advanced manufacturing sectors where conventional superalloys reach thermal or chemical limits, offering potential for enhanced strength retention at elevated temperatures and improved oxidation resistance compared to nickel-based alternatives.

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.
