· Ti2N

Ti₂N is a titanium nitride compound—a hard, ceramic-like intermetallic that forms when nitrogen is incorporated into titanium at elevated temperatures. It belongs to the family of transition metal nitrides and is valued for its exceptional hardness, high melting point, and chemical stability. Ti₂N is used primarily in wear-resistant coatings, cutting tools, and high-temperature structural applications where both hardness and thermal stability are critical; it is often applied as a Physical Vapor Deposition (PVD) coating or incorporated into composite systems. Engineers select Ti₂N over softer titanium alloys when extreme abrasion resistance or erosion protection is needed, and over pure ceramics when some fracture toughness or adhesion to titanium substrates is advantageous.

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.
