· JVASP-41892· TaAlOs2

TaAlOs2 is a tantalum-aluminum oxide compound that belongs to the mixed-metal oxide family, combining the high-temperature stability of tantalum with aluminum's lightweight characteristics. This material is primarily of research and developmental interest for applications requiring extreme hardness, chemical inertness, and thermal stability, positioning it as a candidate for aerospace coatings, wear-resistant surfaces, and high-temperature structural applications where conventional oxides reach their limits.

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.
