Co8 Si4
metal· Co8 Si4
Co8Si4 is an intermetallic compound in the cobalt-silicon system, representing a stoichiometric phase that combines cobalt's strength and magnetic properties with silicon's hardness and thermal stability. This material is primarily of research and specialized high-temperature interest, used in contexts requiring hard, thermally stable phases such as wear-resistant coatings, composite reinforcement, or high-temperature structural applications where conventional cobalt alloys may soften. Co8Si4 is notable for its potential to provide superior hardness and oxidation resistance compared to single-phase cobalt, though it remains less common in production than established superalloys or tool materials.

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.
