· JVASP-79606· VFeCoSi

VFeCoSi is a quaternary high-entropy alloy (HEA) composed of vanadium, iron, cobalt, and silicon in roughly equiatomic proportions. This material belongs to the emerging class of multi-principal element alloys designed to achieve unique combinations of strength, ductility, and thermal stability through compositional complexity rather than traditional precipitation hardening. While primarily in the research and development phase, VFeCoSi is being explored for structural applications requiring simultaneous improvements in mechanical performance and oxidation resistance at elevated temperatures, positioning it as a potential alternative to conventional superalloys and specialty steels in demanding aerospace and energy sectors.

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.
