Aluminum welding wire is pure aluminum welding wire and the aluminum content is over 99.7%. It is a versatile, general-purpose welding material. Special feature: Excellent Welding Results - The welding results are plump and smooth due to the internal powder. It has a low melting point (647 °C ~ 658 °C), good weldability and corrosion resistance, high thermal conductivity, high electrical conductivity and excellent processing performance. No Solder Powder - No need to use other flux powders with aluminum alloy core and base coat. Very handy and easy to solder. Widely used in life - suitable for welding or alloys with high welding strength, good forgeability and good corrosion resistance of the coating. Mainly used for argon arc welding and pure aluminum filler material, aluminum material connecting bus bar and guide rod, electrolytic aluminum plant, as well as electric power, chemical industry, food etc. - it is widely used. Lightweight and Small - 500 x 2mm in size and weighs 3.5g, very
