· JVASP-146682· Ta3AlCo8

Ta3AlCo8 is a ternary intermetallic compound composed of tantalum, aluminum, and cobalt, belonging to the family of high-density metallic intermetallics. This material is primarily of research and development interest, as it combines the high melting point and corrosion resistance of tantalum with the lightweight properties of aluminum and the strength characteristics of cobalt, making it a candidate for advanced high-temperature structural applications. Its development reflects ongoing efforts in materials science to engineer intermetallics with improved strength-to-weight ratios and thermal stability beyond conventional superalloys, though industrial adoption remains limited and applications are largely experimental.

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.
