· JVASP-71787· BeSi2W

BeSi2W is a ternary intermetallic compound combining beryllium, silicon, and tungsten, belonging to the family of refractory metal silicides. This is a research-grade material rather than a commercially established alloy, developed to explore high-strength, lightweight compositions for demanding thermal and structural applications. The material combines the low density of beryllium with the refractory properties of tungsten and the strengthening effect of silicon, making it of interest for aerospace and high-temperature engineering contexts where weight savings and thermal stability are critical.

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.
