· JVASP-65081· K4BeW

K4BeW is a beryllium-tungsten intermetallic compound belonging to the refractory metal alloy family, characterized by the combination of beryllium's low density with tungsten's high melting point and hardness. This material is primarily of research and specialized industrial interest, valued in aerospace and high-temperature applications where lightweight refractory properties are critical, though its beryllium content requires careful handling due to toxicity concerns. The beryllium-tungsten system offers potential for ultra-high-temperature structural applications and advanced composites where conventional superalloys reach their limits.

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.
