Aluminium Gas Welding Flux

Welding flux Alumax  TYPICAL APPLICATIONS •Bicycle industry •Air conditioning system •Car cooling system Directions •First steps: Base metals should be cleaned thoroughly to remove the surface dirt, grease and other impurities Cleaning heavily oxidized surfaces may be applied other methods such as steam jet, wire brushing, or mechanical grinding •Seconds steps: Heat the end of filler metal rod and dip into flux, or sprinkle flux on work-piece, or can be mixed with water or methyl, ethyl or isopropyl alcohol to form a paste •Third steps: Continue heating until the flux liquefies and flows then fills the joint, producing shiny fillets The flux wets the joining surfaces thoroughly and prevents the aluminum oxide inclusions in the joints
