CsNa Alloy (Cesium–Sodium Alloy)

High-Purity Alkali Metal Alloy for Research and Specialty Applications

Our CsNa alloy is a precision-prepared blend of Cesium (Cs) and Sodium (Na), manufactured under strict inert conditions to ensure exceptional purity and stability. This reactive alkali metal alloy is valued for its low melting point, metallic conductivity, and use in photoemissive materials, getter systems, and advanced chemical research.
