Tinplate is made by applying a thin layer of tin to wrought iron or steel. It is often used to prevent rust.
The main use of tinplate is to make tin cans used to package food and many other products, as well as various household utensils.
Tinplate has excellent properties and can be used in a wide range of applications, including:
Beer and Soft Drink Cans
General canned food
Crown and screw caps
electrical parts
oil filter parts
wire shielding material
The process of creating tinplate is also known as tinning.
Tinplate is a thin sheet of steel or iron coated with a tin coating by dipping into molten metal or by electroplating; almost all tinplate is produced today by electroplating. Electrolytic tinplate is classified as follows:
Tempering degree
Tin block
steel type
Annealing method
surface treatment
Tinplate is subject to various corrosion processes. The types of corrosion it faces are:
Filiform Corrosion - Occurs under thin coatings of tin. It is distributed throughout the tinplate in the form of filamentous filaments. These often clump and crack the coating.
Pitting - Occurs on specific areas of the surface. It usually occurs due to dirt particles sticking to the tinplate. It can also be caused by waterline corrosion, crevice corrosion and concentration cell corrosion.
Erosion Corrosion - Occurs slowly over time. It happens after the tinplate has been open to things like water or air for too long. Corrosion starts with a small bubble and continues on the corrosion path.
