· JVASP-51231· TaTiAl

TaTiAl is a refractory metal alloy combining tantalum, titanium, and aluminum, belonging to the family of high-temperature structural metals. This composition is primarily of research and development interest for extreme-environment applications where conventional superalloys reach their performance limits, particularly in aerospace and energy sectors seeking materials with improved high-temperature strength and oxidation resistance compared to single-element or binary refractory systems.

Regulatory Screening

Environmental

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.
