· NbRu3

NbRu3 is an intermetallic compound combining niobium and ruthenium in a 1:3 stoichiometric ratio, belonging to the family of high-refractory metallic intermetallics. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in extreme-temperature structural applications and aerospace systems where conventional superalloys reach their limits. NbRu3 is notable for its refractory character and high density, making it a candidate for high-temperature engine components, but engineering adoption has been limited due to challenges in manufacturing, brittleness at lower temperatures, and cost compared to established alternatives like Ni-based superalloys.

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.
