· AlTiN3

AlTiN3 is a ternary ceramic nitride compound combining aluminum, titanium, and nitrogen, belonging to the family of transition metal nitrides used in hard coating and wear-resistant applications. This material is primarily investigated for protective coatings on cutting tools, wear surfaces, and high-temperature components where superior hardness and thermal stability are required compared to conventional binary nitrides like TiN. The addition of aluminum to titanium nitride enhances oxidation resistance and hardness, making it particularly valuable in machining operations and industrial wear protection, though it remains less widely adopted than established alternatives like CrN or multi-layer TiN/AlN systems.

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.
