Ti3Al
metal· Ti3Al
Ti3Al is an intermetallic compound based on titanium and aluminum, representing a lightweight metallic phase that forms within titanium-aluminum alloy systems. It is primarily of research and developmental interest rather than a standalone commercial product, but serves as a critical constituent phase in gamma titanium aluminide (γ-TiAl) alloys used in high-temperature aerospace applications. Engineers encounter Ti3Al as a strengthening phase in advanced turbine blade and engine component alloys where its contribution to creep resistance and high-temperature stability makes it valuable for next-generation propulsion systems operating beyond conventional nickel-superalloy limits.

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.
