Aluminium bar is a pure aluminium welding wire with an tin content greater than 99.7%. It is a kind of universal welding material with wide application. Features: Fine welding effect, with full or smooth welding effect because of internal powder. With low melting point, fine weldability and corrosion resistance, high thermal conductivity, high electric conductivity and fine processing performance. Very wide application. It is mainly used for argon arc welding and filling material for pure aluminium, connection with aluminium bus and guide rod of electrolytic aluminium plant and electric power, chemistry, food and so on. No need solder powder. You don’t have to use other flux powder with aluminium as the welding core and coating as the salt base. Very convenient and easy to weld. Widely use in life. Suitable for welding or surfacing welding alloy with high strength, fine forgeability and fine corrosion resistance. Light weight and small volume, very easy to bend or carry.
