· CoAlON2

CoAlON2 is a ceramic compound in the cobalt-aluminum oxynitride family, combining metallic and ceramic phases to achieve enhanced hardness and thermal stability. This material is primarily investigated in research and advanced coating applications where wear resistance and high-temperature performance are critical, particularly as a hard coating for cutting tools, tribological surfaces, and potentially thermal barrier applications in aerospace systems.

Regulatory Screening

Environmental

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.
