· JVASP-143774· Ti4FeNi

Ti4FeNi is a titanium-based intermetallic compound containing iron and nickel as primary alloying elements, belonging to the family of titanium aluminides and intermetallic materials. This material is primarily of research and development interest, investigated for high-temperature structural applications where lightweight combined with elevated-temperature strength and stiffness are critical; it represents the broader class of advanced intermetallics being explored as alternatives to conventional superalloys in aerospace and energy sectors, offering potential weight savings at modest cost compared to nickel-based superalloys, though engineering adoption remains limited pending resolution of room-temperature ductility and manufacturability challenges.

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.
