· TiAlN3

TiAlN3 is a ternary ceramic compound in the titanium aluminum nitride family, combining titanium, aluminum, and nitrogen in a stoichiometric ratio. It is used in hard coating applications, particularly for cutting tools, wear-resistant surfaces, and high-temperature structural components where improved hardness and thermal stability are required over binary TiN or AlN compounds. The material is notable for potentially offering enhanced hardness, oxidation resistance, and thermal properties compared to conventional binary nitrides, making it of interest in machining, aerospace, and industrial wear applications.

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.
