Amtec 440S is a unique "Dual Coat" flux coated aluminum electrode that allows the welder to use it as a welding electrode or a torch brazing alloy. It has a special extruded smooth-coated double coated flux that helps give it moisture resistance. This electrode can be used in all positions, has good corrosion resistance, and gives a dense, porosity free deposit, without excessive spatter and fuming. Amtec 440S has good color match to aluminum, but is not recommended for anodizing. The pure white flux coating outlasts conventional products in moisture resistance.
