Zinc-nickel is commonly used to prevent corrosion, that is, premature corrosion of the material. In addition, zinc-nickel can be used as a substitute for cadmium in the galvanic reaction. The purpose of this coating is to reduce corrosion caused by the reaction of different metals. Zinc-nickel plating is an efficient, economical coating with minimal impact on the environment. The information about nickel is as follows: • Contains other metals such as tin or tungsten; Nickel electroplating provides parts with exceptional durability, hardness and electrical conductivity suitable for a wide range of applications; • Surface finishing of similar parts is possible; • More flexibility in plating and thickness; • This method can be used to plate corners and blind holes to maintain the thickness for a long time.
