ReAu
metal· JVASP-132620· ReAu
ReAu is a rhenium-gold alloy combining two of the densest metallic elements, offering exceptional density and potential for high-temperature stability. This material appears in specialized aerospace and medical applications where extreme density, corrosion resistance, or radiation shielding properties are required, though it remains relatively uncommon due to cost and processing complexity. Engineers typically consider ReAu for ultra-compact, demanding applications where the cost of precious metals and rare elements can be justified by performance requirements or where conventional alternatives cannot meet density or thermal constraints.

Export Control
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.
