· JVASP-155270· Ta3Al

Ta₃Al is an intermetallic compound in the tantalum-aluminum system, representing a brittle ordered phase that forms at specific composition ratios between these two elements. This material is primarily of research and development interest rather than established commercial use, as intermetallic compounds in this system are investigated for high-temperature structural applications where their ordered crystal structure offers potential stiffness and thermal stability benefits.

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.
