· Ti3AlC2

Ti3AlC2 is a ternary ceramic compound belonging to the MAX phase family—materials that combine metallic and ceramic properties through a layered crystal structure of transition metals, elements like aluminum, and carbon. This material exhibits unusual damage tolerance and machinability for a ceramic, along with high-temperature stability and thermal shock resistance, making it attractive for extreme environment applications where traditional brittle ceramics fail. Ti3AlC2 remains primarily a research and development material, with potential applications in aerospace, nuclear, and thermal protection systems where the combination of ceramic strength with metallic workability offers significant engineering advantages over monolithic ceramics or conventional alloys.

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.
