· Ti0.99Nb0.01NiSn

Ti0.99Nb0.01NiSn is a quaternary titanium-based intermetallic alloy combining titanium, niobium, nickel, and tin—a composition that positions it within the family of advanced shape-memory and high-temperature metallic materials. This is a research-stage material designed to explore property combinations from the TiNiSn system with modified niobium content, likely targeting applications requiring controlled thermal response, damping characteristics, or enhanced high-temperature stability. While TiNiSn-family alloys are known for shape-memory effects and thermoelastic martensitic transformations, this specific minor-substitution variant represents materials development work aimed at optimizing transformation temperatures, mechanical damping, or thermal conductivity for specialized aerospace and precision engineering contexts.

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.
