Ta3Au
metal· Ta3Au
Ta3Au is an intermetallic compound combining tantalum and gold in a 3:1 ratio, belonging to the refractory metal alloy family. This material is primarily of research and exploratory interest rather than a widely established commercial alloy, studied for applications requiring the combined benefits of tantalum's corrosion resistance and high melting point with gold's noble metal properties. Engineers would consider Ta3Au in specialized high-temperature, corrosion-resistant, or biocompatible applications where the unique properties of this intermetallic phase offer advantages over single-metal solutions or conventional alloys.

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.
