Welding-Flux Sodium Cryolite Na3AlF6 White Powder For Welding Rods Wires

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.

• Effective Fluxing Agent: Improves slag fluidity and oxide removal, producing cleaner weld deposits.
• Lower Melting Point: Helps the flux system melt and flow properly for smooth welding operation.
• Consistent Purity: Uniform Na3AlF6 content ensures predictable flux performance batch after batch.
• Controlled Particle Size: Fine, uniform powder disperses evenly in flux coatings and cored wire fillings.
• Reduced Weld Defects: Contributes to reduced porosity and inclusions for higher-quality welds.
• Brazing Compatibility: Suitable for brazing flux formulations requiring stable fluoride-based fluxing.
