Properties of Tin Plates
1. Rust-Resistant
Tin plating has excellent corrosion resistance and prevents the formation of rust.
Tin does not dissolve easily in water, and as long as the tin plating does not peel off, it can prevent oxidation of iron.
However, if the tin plating peels off and the iron comes into contact with water, the iron will dissolve into the water and rust the iron because iron has a greater ionization tendency than tin.
Ionization tendency refers to how easily an element loses electrons when it becomes an ion, i.e.,
its tendency to give up electrons when it forms an ion.
The greater the ionization tendency, the more easily the element loses electrons and tends to produce stronger cations.
2. Beautiful Surface
Tin plating allows tin to be plated evenly on the steel sheet surface, resulting in a smooth surface.
Tin also reflects light well, resulting in a beautifully shining finish.
3. Suitable for Welding and Soldering
The tin coating is a mixture of iron and tin, which makes it easy to weld and solder.
Since the tin plating layer is a mixture of iron and tin, when welded or soldered, the metals mix and connect with each other
to form a strong bonding surface.
Soldering is a method of joining metal parts together using an alloy called solder.
Solder is generally composed of metals such as tin (Sn), copper (Cu), silver (Ag), and lead (Pb),
which have a low melting point and can be heated to melt to form a metal-to-metal bond.
Solder is generally an alloy of tin (Sn) and lead (Pb).
However, lead-free solder is now widely used due to environmental and health concerns.
Lead-free solder is an alloy made mainly from metals such as tin (Sn), silver (Ag), and copper (Cu) and does not contain lead.
4. Corrosion Resistance
Tin Plate is a low-carbon steel sheet with a tin-plated surface treatment.
The tin-plated film is a mixture of iron and tin, and the strength of the tin-plated layer is enhanced by the mixture of iron and tin.
The tin plating layer makes the surface of tin plate more resistant than iron to chemicals such as moisture, oxygen, acidity,
and alkalinity.
In particular, it prevents oxidation and corrosion caused by chemicals present in the air, such as moisture and oxygen,
and prevents surface rusting.
Tin plate is also resistant to corrosive chemicals such as acidic and alkaline chemicals, making it a highly durable material.
5. Functions as a Solid Lubricant
Tin Plate's tin-plated layer makes the surface slippery and smooth, improving the workability of steel sheets.
It is especially suitable for mass production such as press work.
