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.

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.

Chrome plating in a decorative nickel-chrome system provides a tarnish resistant,pleasing bluish, brilliant, clear deposit on nickel plating. The deposit is hard and therefore resistant to abrasion and wear. Due to these properties, a very thin coating of 0.25 to 0.8 microns of chrome provides a durable and attractive finish. Thick hard chrome deposits are employed where good surface hardness, abrasion, wear resistance and anti-seize properties are desired. Hard Chromium is widely used for gauges, cutting tools, metal forming, drawing dies, machine parts such as piston rings, cylinder liners, crank shafts for marine and aeroplane engines, bearings hydraulic gears, salvage of worn and defective machinery parts, moulds and printing rollers.

Copper electrodeposition has a variety of applications in metal finishing. An undercoat for surface finishes such as nickel chromium electrodeposits on steel, aluminum, zinc bases die-castings and plating grade plastics (ABS). As a base for oxidized or coloured finishes and other metals. In the production of electronic printed circuit boards and of electro types and printing surfaces. Electroforming of precision components and moulds. Thick deposits applied to steel as a stop-off coating in case hardening processes such as carborising and nitriding.

Electroless Nickel (EN) plating is a process of plating Nickel Phosphorous/Boron Alloy by chemical reduction on catalytic metal surface without electric current. Electroless Nickel can be coated on variety of substrates. Electroless Nickel coatings are used in a wide range of industries such as automotive, aerospace, electronic, medicals, chemical processing, oil and gas, etc. Features : Excellent deposit uniformity, Outstanding corrosion resistance, High hardness as that of hard chrome, Low porosity, Solderability, Excellent wear and abrasion resistance.
