Abstract The corrosion behavior of pure copper and copper-clad steels in soil at Dagang district was investigated by burying test in nature field for one year with weight-loss measurement, as well as macro-morphology observation, characterization of corrosion products by SEM and XRD. The results showed that the corrosion rates for pure copper, electroplating copper-clad steel and continuous casting copper-clad steels are 1.01, 1.05 and 1.07 g/(dm2a), respectively. The average corrosion rates of electroplating copper-clad steel and continuous casting copper-clad steel are roughly equal, and that of pure copper is slightly lower than copper-clad steels. Inhomogeneous general corrosion occurs mainly on the pure copper and copper-clad steels in soil at Dagang district, with the different corrosion degree. The corrosion products of pure copper and copper-clad steels consist of Cu2O, Cu(OH)2, CuCl.
