· Ti2AlN

Ti2AlN is a ternary ceramic compound belonging to the MAX phases (metal-aluminum-nitride family), which are layered nanolaminate materials combining metallic and ceramic characteristics. This material exhibits high hardness and stiffness while maintaining some damage tolerance through its layered crystalline structure, making it attractive for applications requiring wear and thermal resistance. Ti2AlN is primarily investigated in research and emerging industrial contexts for protective coatings and high-temperature structural applications where conventional ceramics would be too brittle or where metallic alternatives lack sufficient hardness.

Export Control

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.
