· Nb1 Ir3

Nb₁Ir₃ is an intermetallic compound composed of niobium and iridium in a 1:3 stoichiometric ratio, classified as a semiconductor. This material belongs to the family of refractory intermetallics and represents an experimental research composition rather than a widely commercialized engineering material. Nb-Ir intermetallics are of interest in high-temperature applications and materials science research due to the combined properties of niobium (refractory, lightweight) and iridium (extreme hardness, corrosion resistance), though practical deployment remains limited to specialized research and development contexts.

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.
