Aluminum Welding Wire is pure aluminum welding wire containing more than 99.7% aluminum. It is a kind of universal welding material with wide application. Features: Excellent welding effect - With full & Inner powder smooth welding effect. With a low melting point (647°C~658°C), great! Weldability and corrosion resistance, high thermal conductivity, high electrical conductivity and excellent processing performance. No need solder powder - No need to use other aluminum alloy flux powder as solder core and coating as salt base. Very practical and easy to solder. Widely used in life - Suitable for welding or hardfacing High strength alloy, good forgeability and good corrosion! Resistance. Very wide application - It is mainly used for argon arc welding and pure aluminum filler material, connection with aluminum bus and guide rod of aluminum electrolytic plant and power electrical, chemical, food, etc. Lightweight and small volume - 500*2mm & 3.5g weight, very easy to fold and carry.
