Type of copper alloy welding wire

S201 special copper wire meets GB SCul898 equivalent to AWS ERCu Description: HS201 contains a small amount of deoxy copper welding wire such as silicon, manganese and phosphorus. The addition of tin improves the fluidity of the molten copper. The welding of red copper has the advantages of excellent brazing technology, good weld shape, high mechanical properties, good crack resistance and high mechanical properties. Application: suitable for argon arc welding, gas welding and plasma arc welding of copper. For example, billet continuous casting mould, steelmaking plant electrode clamp, conductive roller, conductive plate, heating original, copper container and copper sculpture. S211 silicon copper wire meets GB SCu6560 equivalent to AWS ERCuSi-A Description: HS211 contains a small amount of manganese silicon bronze welding wire, melting point of about 910-1025 degrees C, good plasticity. Because of the addition of manganese, the welded parts have good mechanical properties, corrosion resistance and wear resistance. The welding process is good. Use: for the arc welding of silicon bronze, copper, brass and copper and steel. It can also be used for the surfacing of steel and cast iron, such as the friction surface of heavy machinery and locomotive and rolling stock. The galvanized steel plate used for argon arc brazing is more often used in automobile door frame and motorcycle parts because of its good corrosion resistance, less burning loss of galvanized layer and good corrosion resistance of brazed joint. S213 phosphor bronze wire meets GB SCu5210 equivalent to AWS ERCuSn-C Description: HS213 is a phosphor bronze wire with high tin content. The tin content increases the hardness and wear resistance of the weld metal, but also increases the hot brittleness tendency. The weld is well formed. Application: it is suitable for argon arc welding of copper, such as copper or phosphorous bronze, especially for repairing copper castings with connection welding of brass and steel. It can also be used for brazing of steel and brazing of steel and cast iron. S214 aluminum bronze wire meets GB SCu6100 equivalent to AWS ERCuAl-A1 Description: HS214 is an iron free aluminum copper wire, which can resist wear and tear under light load, and is resistant to corrosion of seawater, brackish water and common acids. Application: argon arc brazing for aluminum plated steel plate, surfacing of propeller, slide rail, slide surface and bearing surface of ship, welding and surfacing of gray cast iron in mechanical manufacturing, chemical industry and shipbuilding industry, argon arc welding of corrosion resistant aluminum copper or special brass pipe. S215 aluminum iron and copper wire meets GB SCu6180 equivalent to AWS ERCuAl-A2 Description: HS15 is an iron free aluminum bronze wire, which is resistant to abrasion and seawater and acid corrosion. It has good mechanical and welding properties. Use: it is usually used to weld similar components of aluminum bronze, manganese silicon bronze, some copper nickel alloys, iron based alloys and dissimilar metals (such as aluminum bronze and steel, steel and steel). It is also used for surfacing of wear-resistant and corrosion-resistant surfaces. It can also be used for flame spraying. S216 aluminum iron bronze wire meets GB SCu6327 Description: HS216 is a nickel nickel bronze welding wire with low nickel. It has higher mechanical properties and wear resistance than ordinary aluminum bronze, and has excellent corrosion resistance. Application: suitable for welding and welding of aluminum and nickel bronze castings and forgings. It is also used for hardfacing of steel to improve wear resistance and good resistance to seawater erosion. The use range includes shipbuilding, mechanical manufacturing, instrument and machine pump manufacturing. It is also recommended that argon arc brazing for aluminum plated steel plate is also recommended. S221 brass welding end conforms to GB SCu6810A Description: HS221 is a special brass wire with a small amount of tin and silicon. Tin can improve the fluidity of welding wire, while silicon can effectively control zinc evaporation and eliminate pores, resulting in good welding performance. Application: it is suitable for gas welding of brass and copper as filler material, and is also widely used in brazing steel and cast iron and inlaid carbide cutting tools. It can also be used as a surfacing material for low pressure valve sealing surface and light load wear-resistant surface. S231 copper wire meets GB SCu7158 equivalent AWS ERCuNi Description: HS231 is a white copper wire containing 30% nickel. Adding nickel into copper can strengthen weld metal and improve corrosion resistance, especially seawater corrosion resistance. The weld metal has good thermal and cold ductility. Application: it is suitable for welding and surfacing of copper nickel alloy under 30% nickel content, such as argon arc welding of seawater corrosion resistant container, condenser tube, cooler and heat exchanger. It can also be used for surfacing of carbon steel parts with seawater corrosion resistance. The welding wire is also recommended for joint welding of copper nickel and copper steel dissimilar metals. S232 copper wire meets GB SCu7061 Description: HS232 is a copper welding wire with 10% nickel. The addition of nickel strengthens weld metal and improves corrosion resistance, especially seawater corrosion resistance. The weld metal has good thermal ductility and cold ductility. Application: it is suitable for 10% nickel welding and surfacing of white copper, such as seawater corrosion resistant container, cooler, argon arc welding of heat exchanger.
