· JVASP-66727· BeCuHg

BeCuHg is a ternary metallic alloy combining beryllium, copper, and mercury. This material represents an experimental or specialized composition in the beryllium-copper family, where mercury addition modifies mechanical properties or processing characteristics. The incorporation of mercury is highly unusual in modern engineering alloys due to toxicity and volatility concerns, suggesting this composition is primarily of historical or research interest rather than current industrial practice.

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.
