· Zr0.35Hf0.35Ti0.3NiSn

Zr0.35Hf0.35Ti0.3NiSn is a high-entropy alloy (HEA) combining refractory metals (zirconium, hafnium, titanium) with transition metals (nickel) and a semimetal (tin). This is a research-stage material designed to achieve exceptional thermal stability and mechanical performance at elevated temperatures through multi-component strengthening mechanisms. While not yet widely commercialized, alloys in this family are being developed for aerospace and nuclear applications where conventional superalloys reach their thermal limits, with the multi-principal-element design intended to provide superior creep resistance and thermal fatigue tolerance compared to traditional single-matrix superalloys.

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.
