· JVASP-142017· AlCrN2

AlCrN2 is an aluminum chromium nitride ceramic coating material, likely a hard ceramic compound in the ternary AlCrN system. This material family is engineered for extreme surface hardness and thermal stability, typically applied as a protective coating rather than used as a bulk material. It is employed in metal cutting and forming operations where resistance to wear, oxidation, and thermal shock is critical, and it offers improved performance over binary nitride coatings in high-speed machining environments.

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.
