Ta4CoNi
metal· JVASP-104688· Ta4CoNi
Ta4CoNi is a refractory high-entropy or multi-principal-element alloy combining tantalum, cobalt, and nickel, designed for extreme-temperature and high-strength applications. This material family is primarily investigated in research and advanced aerospace contexts where conventional superalloys reach their performance limits, offering potential advantages in elevated-temperature strength, wear resistance, and thermal stability. Engineers would consider Ta4CoNi for next-generation turbine engines, hypersonic vehicle structures, or specialized tooling applications where weight efficiency and thermal performance justify the material's cost and processing complexity.

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.
