1) welding wire with low melting point 2) the welding wire has various specifications for choosing 3) Subtle working propertie The main materials of BAg40CuZnSn silver welding wire include silver, copper, zinc and tin. Among them, the percentage of silver reaches 40. The addition of tin can decrease the melting point and promote the shape of solder joint.BAg40CuZnSn welding wire is widely used in the welding of refrigeration, electrical household appliances, machinery, aviation, automobile, eyeglass, instruments and meters, hard metal, tools and gauges, stainless steel ware and other industries. Besides the vacuum furnace brazing, it will gain better solder joint if it together uses with brazing flux.Our company is specialized in manufacturing welding materials and other alloy materials. It is a technology-oriented privately enterprise which has its own technological research center , strong technological force, advanced equipment and be the corporate champion in the intermediate temperature welding material in China.
