TaAl3
metal· TaAl3
TaAl3 is an intermetallic compound combining tantalum and aluminum, belonging to the family of refractory metal aluminides. This material is primarily of research and development interest rather than a widely deployed commercial alloy, studied for its potential in high-temperature structural applications where the combination of tantalum's refractory properties and aluminum's lightweight characteristics offers theoretical advantages in specific strength and thermal stability.

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.
