· HoIr

HoIr is an intermetallic ceramic compound combining holmium and iridium, representing a high-density refractory material from the transition metal ceramic family. This is a specialized research and development material explored for extreme-environment applications where thermal stability, mechanical rigidity, and resistance to oxidation are critical. Engineering interest in HoIr centers on its potential for high-temperature structural use and its position in the broader class of rare-earth/refractory metal intermetallics being investigated as alternatives to conventional superalloys in demanding aerospace and nuclear contexts.

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.
