Jiaozuo Eversim produces welding-flux sodium cryolite (Na3AlF6) white powder used as a fluxing agent in the manufacture of welding rods, wires, and brazing consumables. Cryolite lowers the melting point of the flux system, improves slag fluidity, and helps remove oxides from the weld pool, producing cleaner, higher-quality welds. Our welding grade is manufactured with consistent purity and particle size to ensure reliable performance in flux formulations. Key Features:
