· B2 Ni2 Nb2

B2 Ni₂Nb₂ is an intermetallic compound based on the nickel-niobium system, classified as a semiconductor with a B2 (CsCl-type) ordered crystal structure. This is primarily a research material rather than a commercial alloy, studied for its potential in high-temperature structural applications where the combination of nickel and refractory niobium offers interesting mechanical properties. The compound belongs to the broader family of nickel-niobium intermetallics, which are investigated as candidates for advanced aerospace and extreme-environment applications where conventional superalloys may reach their limits.

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.
