Aluminum Brazing Welding Wire

Flux Cored Aluminium Brazing Welding Wire is a kind of aluminum-silicon solder with aluminum flux (potassium fluoro aluminate and other active agents). It 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.

CHAL Aluminium Corporation has more than 14 years of experience in supplying welding materials. We are specialized in manufacturing all kinds of welding materials and fittings such as aluminum brazing welding wires, aluminum flux-cored brazing wires, mild steel welding wires, submerged arc welding wires, argon arc welding wires, TIG rods, flux-cored wires, and aluminium/aluminum alloy welding wires.

We developed a range of welding wires to cover our customers’ needs. And also, our research and development teams work in close cooperation with our customers to develop tailor-made aluminum brazing welding wire according to their special needs.

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.
