· JVASP-40497· Ta4Ni2C

Ta4Ni2C is a tantalum-nickel carbide compound belonging to the family of refractory metal carbides. This material combines the high melting point and corrosion resistance of tantalum with nickel's toughening effects and carbide strengthening, making it a candidate for extreme-environment applications where conventional superalloys reach their limits. While primarily a research and development material rather than a widely commercialized engineering grade, Ta4Ni2C represents the potential of complex carbide systems to enable next-generation high-temperature structural applications in aerospace, energy, and advanced manufacturing sectors.

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.
