K4BeW
metal· 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.
