Ca4BeW is an intermetallic compound combining calcium, beryllium, and tungsten—a research-phase material rather than an established commercial alloy. This ternary system belongs to the family of lightweight refractory intermetallics, where the combination of beryllium and tungsten creates potential for high-temperature applications requiring low density and stiffness. Industrial use remains limited; the material is primarily of interest in aerospace and materials research communities exploring next-generation high-temperature structural alloys, though processing, brittleness, and beryllium toxicity present significant engineering and manufacturing challenges.
