Uses of Electroplating
1.Electroplating is a very useful process and is widely sued in the industry for coating metal objects� with a thin layer of a desired metal. The metal is deposited in the form of a thin layer has some properties which the metal of the object does not possess.

2. Chromium metal has shiny appearance and does not corrode . Chromium metal is however quite expensive and hence it is not economical to make whole object out of chromium. So, the object� is made of cheaper metal like iron or steel and only a thin coating of chromium metal is deposited all over its surface by electroplating.� example, chromium plating is done on bicycle bells, wheel rims, bathroom fittings , LPG stoves etc

3. Tin metal has shiny appearance, it does not corrode and it is non-poisonous. It is less reactive than iron. Tin cans used for storing food are made by electroplating tin metal on to iron. Due to tin plating over the surface of iron, the food does not come in contact with iron and is protected from getting spoilt. In fact, the less reactive and shiny metals like chromium, tin and nickel are electroplated on more reactive and dull looking metals like iron and steel to protect them from corrosion and give them an attractive finish.

4. Electroplating is used to give objects made of a cheap metal a coating of a more expensive metal to make them look more attractive.
