· JVASP-26047· Co21Re2B6

Co21Re2B6 is a cobalt-rhenium boride intermetallic compound belonging to the family of refractory metal borides. This is a research-stage material explored primarily for its potential high-temperature strength and hardness characteristics, combining cobalt's established use in superalloys with rhenium's exceptional refractory properties and boron's hardening effects. Industrial deployment remains limited; the material is of interest to researchers investigating advanced wear-resistant coatings, high-temperature structural applications, and tool materials where conventional superalloys or ceramic composites may be insufficient.

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.
