Electroplating
Zinc and Zinc Alloys
Zinc plating offers an economical option for decorative and industrial finishes on metallic substrates. It is possibly second to only Nickel with respect to plating applications. Recent developments have focused on alloy plating of zinc with iron, cobalt etc. to produce exotic finishes with exceptional resistance to corrosion and high durability. Depending upon the practicality of your application, you can choose from a conventional high cyanide zinc plating process to the most modern chloride or other non-cyanide alkaline based processes which are, more recently preferred, for environmental reasons.
