· Zr0.25Hf0.25Ti0.5NiSn

Zr₀.₂₅Hf₀.₂₅Ti₀.₅NiSn is a multi-principal-element intermetallic compound belonging to the half-Heusler alloy family, combining refractory metals (zirconium, hafnium, titanium) with nickel and tin. This is a research-stage material currently investigated for thermoelectric and high-temperature structural applications, where the combination of elements is designed to balance thermal transport, mechanical strength, and phase stability across demanding temperature ranges. The half-Heusler structure and compositional strategy—common in thermoelectric materials development—offer potential advantages in converting waste heat to electricity or enabling lightweight, high-temperature components where traditional superalloys may be too dense or costly.

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.
