· JVASP-140779· Ta5Al3C

Ta5Al3C is a tantalum-aluminum carbide composite or intermetallic compound that combines the refractory properties of tantalum with ceramic-phase strengthening from aluminum carbide. This material belongs to the family of high-temperature metal carbides and intermetallics, representing an experimental or specialized composition rather than a widely commercialized alloy. It is primarily of interest in research and development contexts for ultra-high-temperature structural applications where exceptional hardness, oxidation resistance, and thermal stability are required, competing with established refractory metals and ceramic matrix composites in demanding aerospace and industrial settings.

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.
