Co21B6W2
metal· JVASP-53248· Co21B6W2
Co21B6W2 is a cobalt-based intermetallic compound containing boron and tungsten additions, designed to operate in high-temperature and wear-resistant applications. This material belongs to the cobalt superalloy family and is primarily investigated for aerospace propulsion systems, industrial tooling, and hard-facing applications where conventional cobalt alloys reach performance limits. The tungsten and boron additions enhance hardness and high-temperature strength, making it a candidate for applications requiring superior wear resistance and thermal stability compared to standard cobalt-chromium or nickel-based alternatives.
