· V5SiB2

V5SiB2 is a vanadium silicide boride compound representing an advanced refractory intermetallic material designed for extreme-temperature applications. This material combines vanadium, silicon, and boron to achieve high stiffness and thermal stability, making it a candidate for aerospace and power generation environments where conventional superalloys reach their performance limits. While primarily in research and development phases, V5SiB2 belongs to a family of ultra-high-temperature materials being explored to replace or supplement nickel-based superalloys in next-generation turbine systems and hypersonic vehicle structures.

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.
