· NbNi3

NbNi₃ is an intermetallic compound combining niobium and nickel in a 1:3 ratio, belonging to the family of transition-metal intermetallics that exhibit high stiffness and moderate density. This material is primarily explored in aerospace and high-temperature applications where weight reduction and structural rigidity are critical, particularly as a potential reinforcement phase in superalloys and composite systems rather than as a standalone engineering material. NbNi₃ offers advantages over conventional nickel-based superalloys through improved specific stiffness, though its brittleness at lower temperatures and processing challenges make it most relevant in research contexts for next-generation turbine materials and high-performance structural composites.

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.
