NiCuNI: The Nickel-Copper-Nickel(Ni-Cu-Ni) coating has excellent physical and chemical properties, like corrosion resistance, hardness, abrasive resistance
Au： Excellent resistance to high temperature, corrosion and colour changing
Ag： Enhanced corrosion resistance, increasing the conductivity
Epxoy： Epoxy resin has good physical and chemical properties, and has excellent adhesion strength on the surface of the metal and nonmetal materials, good dielectric properties
Zn： Blue white zinc coating is generally thinner than the Ni-Cu-Ni coating and anticorrosion ability is relatively good. Blue white zinc coating after
