· VAu4

VAu4 is an intermetallic compound composed of vanadium and gold, belonging to the class of metallic intermetallics that combine refractory and noble metal elements. This material exhibits high density and significant elastic stiffness, making it relevant for specialized applications requiring excellent strength-to-weight considerations in dense metallic systems. VAu4 is primarily of research and development interest rather than established high-volume industrial use; it represents the broader family of refractory-noble metal intermetallics being explored for high-temperature structural applications, wear-resistant coatings, and specialized electronic or catalytic uses where the combination of vanadium's refractory properties and gold's chemical stability offers unique advantages.

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.
