· YCuPb

YCuPb is a ternary metal alloy combining yttrium, copper, and lead, representing an experimental composition from the rare-earth intermetallic family. This material falls within research-stage metallurgy and is not established as a commercial engineering alloy; its potential lies in specialized applications requiring the unique property combinations that rare-earth elements and heavy metals can provide, such as radiation shielding, high-density components, or thermoelectric applications where yttrium's refractory character and lead's density are leveraged.

Export Control

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.
