· Cr2AlN

Cr₂AlN is a ternary transition metal nitride ceramic coating belonging to the MAX-phase and hard ceramic family, combining chromium, aluminum, and nitrogen. It is primarily used as a physical vapor deposition (PVD) coating for cutting tools, wear-resistant components, and high-temperature applications where it provides exceptional hardness, oxidation resistance, and thermal stability compared to binary nitrides like CrN or AlN alone. The addition of aluminum enhances oxidation resistance and thermal shock performance, making it valuable in extreme machining conditions and industrial processes that demand extended tool life and reduced downtime.

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.
