Brazing of copper and copper alloys

 Brazing of copper and copper alloys Copper has excellent electrical conductivity, thermal conductivity, corrosion resistance, ductility and certain strength. Adding various alloying elements to copper can increase its corrosion resistance, strength and improve machinability. Therefore, copper and copper alloys are widely used in electrical, electrical, chemical, food, power, transportation, aviation, aerospace, weapons and other industrial sectors. Copper and its alloys can be divided into: pure copper, brass, bronze and cupronickel. The mass fraction of pure copper is not less than 99.5%. Pure copper can be divided into oxygen-free copper and oxygen-free copper (deoxidized copper) according to its oxygen content. Deoxidized copper is to add a deoxidizer (such as phosphorus) during the smelting process or use other methods to make the mass fraction of oxygen reach a very low level
