Our industrial aluminium brazing flux powder represents premium joining technology specifically formulated for aluminium and aluminium alloys. With CAS number 60304-36-1, this carefully balanced composition includes KAlF4 (60.0-80.0%), K2AlF5.H2O (20.0-40.0%), and controlled fluoride content (48.0-54.0%) with minimal impurities. The product features a solidus temperature of 540-570°C, consistent particle size distribution (D50 15.0-50.0µm), and bulk density of 0.80-1.20g/ml after tapping. This precise formulation ensures excellent oxide removal, superior wetting properties, and clean brazing operations without equipment clogging or excessive residue buildup, providing reliable performance in critical manufacturing environments.

This aluminium brazing flux serves essential functions across multiple industrial sectors where aluminium joining integrity is paramount. Automotive manufacturers depend on it for radiator and heat exchanger production, while HVAC and refrigeration industries utilize it for evaporator and condenser coil assembly. Aerospace applications benefit from its lightweight component fabrication capabilities, and general metalworking operations apply it for various aluminium structures and systems. The product meets stringent industry requirements by delivering consistent, predictable performance in both automated production lines and manual brazing operations, ensuring high-quality joints that endure operational stresses and challenging environmental conditions.

The business value of this aluminium brazing flux lies in its proven reliability and manufacturing efficiency, directly translating to reduced rejection rates and lower production costs. Manufacturers benefit from exceptional wetting characteristics that create strong, leak-proof joints without requiring excessive flux application. The low impurity content including Na (1.00% max), Ca (0.20% max), Si (0.05% max), Fe (0.030% max), and Ti (0.010% max) ensures minimal corrosion risk and extended product lifespan. With drying loss limited to 5.00% max, the product maintains its effectiveness throughout storage and use, providing predictable performance that serious industrial buyers can trust for their critical manufacturing processes and quality standards.
