· Co21 Re2 B6

Co21Re2B6 is a cobalt-rhenium boride intermetallic compound representing an experimental high-performance alloy system designed for extreme temperature and wear resistance applications. This material belongs to the family of boride-strengthened refractory alloys, combining cobalt's toughness with rhenium's high melting point and boron's ceramic-hardening effects. While primarily a research-phase material, compositions in this family show potential for aerospace propulsion, high-temperature tooling, and extreme-wear environments where conventional superalloys reach performance limits.
