Aluminum Brazing Welding Wire is mainly used for flame brazing aluminum and aluminum alloy, and melting temperature of 582-640 degrees, no need to add flux when welding. Besides, it can effectively reduce defects such as pores and inclusions generated during welding, no need to clean after welding and reduce welding time. So it is the brazing material used for cooling aluminum radiators, aluminum air conditioning pipes, aluminum bicycle frames, automotive air conditioning, and other industries. This wire is suitable for brazing components of various grades.
Main Features of Aluminum Brazing Welding Wire
It can be divided into the flux-cored wire with seam and seamless flux-cored wire.
Suitable for welding or surfacing welding alloy with high strength, good forge ability & good corrosion resistance.
Seamed flux-cored wire of the finished silk copper plating processing, can be in the process of welding wire custody moisture-proof performance and conductivity was better than having a seam in the process of welding flux-cored wire.
With lower melting temperature, no extra flux is needed increasing productivity and fixed flux/filler metal ratio.
With full & smooth welding effect. It has the feature of internal powder, great weldability and corrosion resistance, high thermal conductivity, high electric conductivity, and excellent processing performance.

Matters Needing Attention for Aluminum Brazing Welding Wire:
Wire into the plant must be stored in dry conditions, can not open-wire reel waterproof package.
Welding shall be removed before welding surface oil, rust, water, and other impurities.
The CO2 gas protection, CO2 gas purity 99.98%.
CO2 welding protective gas flow rate should be controlled at 20~25L/min.
Wire extension length should be controlled in the range of 15~25mm.
