Copper and copper alloys are generally classified into four categories copper (pure copper) brass bronze and white copper. Copper brazing properties mainly depend on the stability of the surface oxide film and the influence of the brazing heating process on the material properties. Copper oxide and cuprous oxide can be formed on the surface of pure copper.
