A copper-phosphorus electrode is a specialized welding electrode that comes from a copper alloy made up of phosphorus. This electrode is crafted to utilize the beneficial properties of phosphorus in welding applications. Phosphor Copper Soldering; this is a solder with its basic material being binary copper and phosphorus alloy, it displays nice fluidity, suitable for contact brazing, flame brazing, high frequency brazing and furnace brazing. By adding silver to the phosphorous copper alloy, its wettability can be greatly improved so as to increase strength and toughness and reduce melting point. It’s extensively applied in refrigeration industry as well as motor, electrical appliance, instrument and other manufacturing industries.Sometimes it is used for flame brazing or resistive type/gap filler type/high frequency brazing methods.Copper-zinc solder finds its use mainly in the process of flame treatment together with other processes like resistance/spot-weld solder or high-frequency weldings.For more information about such materials and their applications you may want to get in touch with China Copper-Phosphorus Electrode Manufacturer.
