CrHg
metal· JVASP-127331· CrHg
CrHg is an intermetallic compound composed of chromium and mercury, belonging to the class of binary metal systems with potentially high density. This material exists primarily in research and specialized contexts rather than widespread industrial use, as mercury-based intermetallics present significant handling, toxicity, and environmental challenges that limit practical applications. The chromium-mercury system is of interest in materials research for understanding phase diagrams and intermetallic behavior, but has not achieved adoption in mainstream engineering due to mercury's volatility, regulatory restrictions, and the availability of superior alternatives for most mechanical applications.

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.
