· JVASP-133175· Re7B3

Re7B3 is a rhenium boride ceramic compound belonging to the family of refractory metal borides, materials engineered for extreme-temperature and wear-resistant applications. This material is primarily of research and specialized industrial interest, valued in contexts demanding exceptional hardness, chemical inertness, and thermal stability beyond the capabilities of conventional ceramics or tungsten-based alternatives. Re7B3 finds application in high-performance cutting tools, thermal barriers in aerospace engines, and wear-resistant coatings where conventional ceramics would fail under thermal or mechanical shock.

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.
