TFS

TFS (Tin Free Steel, also known as ECCS, Electro-Chromium-Coated-Steel).

Low carbon steel covered with chromium with a layer between them of steel-chromium alloy. Its price is slightly cheaper than tinplate. It is mainly used for producing can lids or ends, two pieces cans (drawn cans) and crown caps.

Chromium provides very good lacquer adherence. It is not apt for welding.

This material can be supplied in sheets or coils. In the case of sheets, we deliver the material lacquered and printed, as well as with straight or scroll cut.

Even though the minimum thickness can be of 0.10mm, the standard range is between 0.13 and 0.50mm.

Basic Uses of tinplate

  • Food cans: Standard ends, easy-open ends, twist-off caps, crown taps, round or rectangular welded bodies, drawn bodies, and deep drown bodies (DWI).
  • General line cans: Aerosol, ends, tops, rings, welded round or rectangular bodies, welded and expanded bodies, drawn bodies, decorative cans.
  • Other applications:Deep drawn and moderate conformation.
