Prime Quality Electrolytic Tinplate and TFS for Metal Containers

Product Description:

1.Structure of Prime Quality Electrolytic Tinplate and TFS for Metal Containers Description

Also known as chromed steel, tin-free steel (TFS) is obtained by coating the metal base (low-carbon steel) with an ultra-thin layer of metallic chrome and then with a chromium oxide layer.

The product complies with ASTM A-657 Specification and is manufactured with low current density (TFS-III) and is supplied in coils （up to 12 metric tons）or sheets.

2.Main Features of the Prime Quality Electrolytic Tinplate and TFS for Metal Containers

Corrosion resistance – Tinplate has got good corrosion resistance. By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents. Coated items should meet 24 hour 5 % salt spray requirement.

Solderability and weldability – Tinplates can be joined both by soldering or welding. These properties of tinplate are used for making various types of cans.

Hygienic – Tin coating provides good and non toxic barrier properties to protect food products from impurities, bacteria, moisture, light and odours.

Safe – Tinplate being low weight and high strength makes food cans easy to ship and transport.

Eco friendly – Tinplate offers 100 % recyclability.

Tin is not good for low temperature applications since it changes structure and loses adhesion when exposed to temperatures below – 40 deg C.
