· 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.

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.
