· JVASP-128237· TaCu

TaCu is a tantalum-copper binary alloy combining the high density and corrosion resistance of tantalum with copper's thermal and electrical conductivity. This alloy is primarily used in specialized electronics, radiation shielding, and high-reliability applications where the combination of chemical inertness, thermal management, and density is advantageous; it is notably more ductile than pure tantalum while retaining superior corrosion resistance compared to copper-heavy alternatives.

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.
