· JVASP-145245· Zr9Re4B

Zr9Re4B is a zirconium-rhenium boride intermetallic compound belonging to the refractory metal alloy family. This material is primarily of research and developmental interest, designed to combine zirconium's corrosion resistance with rhenium's high-temperature strength and boron's hardening effects for extreme-environment applications. Engineers would consider this material for specialized aerospace and nuclear contexts where conventional superalloys reach their thermal limits, though it remains largely experimental rather than in widespread production use.

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.
