· JVASP-67651· BeCrHg

BeCrHg is a ternary intermetallic compound combining beryllium, chromium, and mercury—a research-stage material that belongs to the family of lightweight, high-stiffness intermetallics. This compound has received limited industrial adoption, but represents an experimental exploration of beryllium-chromium systems for potential aerospace and structural applications where the combination of low density and high elastic moduli could offer weight-critical advantages. The inclusion of mercury is unusual in modern engineering alloys due to toxicity and volatility concerns, making this primarily a laboratory or historical material rather than a mainstream engineering choice.
