Tinplate (ETP) and Tin-free-steel (TFS)

Description

ETP (Electrolytic Tinplate). Low carbon steel coated with tin with a layer between them of steel-tin alloy and destined to be used mainly in the production of metal cans.

Tin provides good weldability and electrical conductivity, as well as high corrosion resistance.

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.

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

Supply

This material can be supplied in sheets or coils. In the case of sheets, we are able to 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 habitual range is between 0.13 and 0.50mm.

In all our products, besides offering standard choices, we could offer other choices of available stocks –“non-prime”, “over-rolling” or “secondaries”– at even more competitive prices and/or with shorter lead times.

Use

There are many different possible uses, but as a way of example we could talk about three big groups:

• 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.
