Tinplate (TP)

Tinplate is the common saying for tin electroplated sheet steel. It refers to the cold rolled low carbon thin steel plate or the steel strip with both sides plated with pure tin. The tin mainly functions for rust and corrosion prevention. The product combines the strength and formability of steel and corrosion resistance, tin soldering property and nice appearance of the tin into a whole to form the material featuring corrosion resistance, no toxicity, high strength, and good ductility.

The superior smoothness and strong adhesion between the tin layers enable the tinplate to have excellent mechanical property and processability. We mainly supply the product to the customers from metal processing field relating to food and beverage packaging, grease tank, chemical can, etc.

Characteristics
1. Low Pollution
The tinplate is the main material for tin container. Actually, it is harmless to the environment for natural decomposition. The tin container can be oxidized naturally to go back to the original iron oxide. So, the discarded tin container can achieve decomposition with time, and won’t pose pollution to the environment. Meanwhile, the manufacturing of the tin container doesn’t need to cut down trees. It won’t destroy the ecological balance.

2. Recycling
The tin can has the special characteristic that other packaging materials don’t have. That is the tin can could be attracted by magnet. Then, we can exploit the magnetic separator to separate the tin can from the waste via the magnetic force. By using the special characteristic, 80% tin cans can be recycled from the waste. Moreover, the invention of the environmental protective cover allows the user to use the tin can more safely and sanitarily. It can also reduce the waste effectively, obtaining the direct and obvious effect to the recovery operation.

3. Resources Saving
In the aspect of removing the pollution residue on the tin can, we can employ the chopping machine to effectively remove over 98% pollutants to provide good quality scrap iron. In addition, the American experts point out that the aluminum easy open end facilitates the reproduction of scrap iron because it can decrease the amount of hot metal during the steel making process and reduce the cost of overall steel manufacturing.

Additionally, in terms of energy saving, compared to using iron ore, using 1t tinplate scrap to manufacture steel can save the natural gas with the amount of 230m³. Therefore, the recycling and reproduction of tin can reduce the impact on the global environment and energy. The tin can meets the future product packaging development trend.

Steel Type
Type Description
MR It is the base steel with low residual elements content. It has excellent corrosion resistance, and is widely used in general applications.
L It is the base steel with extremely low residual elements such as Cu, Ni, Co, and Mo. It has excellent corrosion resistance to certain types of food products.
D It refers to the aluminum-killed base steel used in applications involving deep drawing or other types of severe forming that tends to give rise to Lueders' lines.
