The whole is made of cast iron, which is hard and heavy with high density. The dumbbell surface is electroplated, smooth and refreshing, no rust, no discoloration and can be used permanently.
The process of plating a thin layer of other metals or alloys on some metal surfaces by using the principle of electrolysis. During electroplating, the plated metal is used as anode and oxidized into cation into electroplating solution; The metal product to be plated is used as cathode, and the cation of the plated metal is reduced on the metal surface to form plating layer. In order to eliminate the interference of other cations and make the coating uniform and firm, it is necessary to use the solution containing the plating metal cation as the electroplating solution to keep the concentration of the plating metal cation unchanged. Electroplating can enhance the corrosion resistance of metals (most of the coated metals use corrosion-resistant metals), increase hardness and beautiful surface.
