· JVASP-151565· IrC4

IrC4 is a ceramic composite material based on iridium carbide, combining a refractory metal carbide matrix with enhanced structural properties. This material is primarily investigated for ultra-high-temperature applications in aerospace and materials research, where its combination of hardness, thermal stability, and metallic density makes it attractive for extreme environments that exceed the performance envelope of conventional ceramics or superalloys.

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.
