· JVASP-127022· TaCu3

TaCu3 is an intermetallic compound combining tantalum and copper in a 1:3 ratio, belonging to the family of refractory metal intermetallics. This material is primarily of research interest due to its high density and potential for high-temperature applications, though it remains largely experimental with limited commercial deployment compared to established tantalum alloys or copper-based systems.

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.
