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.
It can be divided into the flux-cored wire with seam and seamless flux-cored wire.
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.
