· LuIr

LuIr is an intermetallic ceramic compound composed of lutetium and iridium, representing a high-density material in the refractory intermetallic family. This is a research-stage material studied primarily for extreme-environment applications where both high melting point and chemical stability are critical. LuIr and related lanthanide-transition metal intermetallics are of particular interest for aerospace and high-temperature structural applications where conventional superalloys reach their limits, though commercial adoption remains limited pending further development of processing methods and cost reduction.

Regulatory Screening

Environmental

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.
