· Ta4 Co8

Ta4Co8 is an intermetallic compound combining tantalum and cobalt in a 1:2 atomic ratio, belonging to the family of refractory metal intermetallics. This material is primarily of research interest for high-temperature structural applications where extreme strength and thermal stability are required, though industrial adoption remains limited compared to established superalloys. The tantalum-cobalt system is investigated for aerospace and power generation contexts where conventional nickel-based superalloys approach performance 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.
