· JVASP-99603· Ta2MoIr

Ta2MoIr is a ternary refractory metal alloy combining tantalum, molybdenum, and iridium—three elements prized for extreme-temperature stability and corrosion resistance. This is a research-stage material composition studied for ultra-high-temperature structural applications where conventional superalloys reach their limits; the combination leverages tantalum's strength, molybdenum's thermal properties, and iridium's oxidation resistance to create a candidate material for next-generation aerospace and energy systems.

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.
