Tin Plating basically can be categorised into tin plating and tin alloys plating. Tin plating is extensively used for food preservation container, electrical, electronic components and bearing surfaces. Tin-lead alloys are basically designed for electronic industries. Tin-cobalt alloys are used as a substitute to chrome plating.

Electrodeposits of Cadmium are used to protect steel and cast iron against corrosion as it is electronegative to iron. Besides having excellent corrosion protective properties. Cadmium plating is employed in the aircraft industries and electrical industries where it has a specific advantage over zinc. These include low contact potential in contact with aluminium, high lubricity, higher resistance to alkalis and to sea water. Cadmium is widely used on moving parts or threaded assemblies as it has natural lubricity, minimal change in dimension due to low voluminous corrosion products. Dull Cadmium Mercury free process having excellent throwing power and yields a matt white deposit, Bright Cadmium Simple to operate, low cost bath for producing bright, uniform eye-appealing Cadmium deposits.

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.

Brass is an alloy of copper and zinc. It is plated on mild steel aluminium and zinc based die-castings for decorative applications. It is plated on mild steel to obtain good bonding of steel to rubber. An undercoat of nickel considerably will increase the aesthetic value of brass plated components. Zinco Brass Process It provides a general purpose economical brass salt for use in bath vat and barrel. It yields a rich golden yellow deposit. The solution can be used in either warm or cold conditions. However bath performance is better in warm conditions. By altering the operating conditions like temp. & current density, the colour of the deposit may vary from pale yellow to reddish gold.

Uniform Black coatings of ferroferric oxide & cupric oxide are produced on mild steel and copper & copper alloys respectively. Beautiful, shiny black coatings are obtained on buffed or polished surfaces. Flat non-reflective coatings are obtained on etched or sand blasted steel.
