· Ti3AlN

Ti3AlN is a ternary ceramic-metal compound combining titanium, aluminum, and nitrogen, belonging to the family of transition metal nitrides and MAX-phase related materials. It is primarily investigated as a hard coating material and structural reinforcement phase in composite systems, valued for its potential to provide high hardness and thermal stability in demanding environments. Applications focus on wear-resistant coatings for cutting tools, protective surface layers in high-temperature machinery, and as a reinforcement constituent in metal-matrix or ceramic-matrix composites, where its combination of strength and nitride-phase stability offers advantages over conventional single-metal or binary nitride alternatives.

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.
