· TaAlNi2

TaAlNi2 is an intermetallic compound combining tantalum, aluminum, and nickel, belonging to the family of refractory metal-based alloys. This material is primarily of research and developmental interest rather than established in high-volume production, positioned for applications requiring exceptional thermal stability, corrosion resistance, and structural integrity at elevated temperatures. The tantalum base provides high melting point and oxidation resistance, while the nickel and aluminum additions contribute to mechanical performance and processability—making this composition a candidate for next-generation aerospace and high-temperature structural applications where conventional superalloys or refractory metals reach their limits.

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.
