· Ti1 Al3

Ti1Al3 is an intermetallic compound in the titanium-aluminum system, classified as a semiconductor material with potential applications in advanced structural and functional devices. This material belongs to the family of titanium aluminides, which are lightweight intermetallic phases that combine titanium and aluminum atoms in fixed stoichiometric ratios. While Ti1Al3 remains primarily a research compound rather than a widely commercialized engineering material, titanium aluminide intermetallics are being investigated for high-temperature structural applications and electronic/photonic device integration where the unique electronic and mechanical properties of ordered intermetallic phases offer advantages over conventional alloys or pure semiconductors.

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.
