Welding flux
Alumax 
KEY FEATURES
•All-purpose Alumax® is designed for torch brazing aluminum
•Brazing flux in finely ground white powder form
•Used to braze common aluminum base materials such as 1100, 3003, and 6061
•Working temperature range 490.5°C-601.6°C
•Use with aluminum brazing filler metals 4047 (718) and 4145
ADVANTAGES
• Formulated to strong the weld joint in aluminum alloys, from oxygen contamination, melting the substrate metals
• Prevent re-oxidation, porosity during the welding process, become a block between the molten weld and the air
• Activity range is perfect with aluminum brazing filler metals
• Effectively reduce the possibility of heat affectation and burn-through of the work piece
