Product Introduction
Tin Free Steel (TFS), also known as Electrolytic Chromium Coated Steel (ECCS), is a chromium-coated steel material designed for metal packaging components such as can ends, lids, and closures. Unlike tinplate, it is not commonly used for can bodies, but is widely applied in parts that require strong coating adhesion and precise forming performance.
With excellent lacquer adhesion, good formability, and cost efficiency, TFS is a practical choice for applications where painted or coated surfaces are required. Its clean and stable surface supports consistent processing and reliable performance. It is commonly used in easy open ends, bottom ends, caps, and various industrial packaging components. Available in coil and sheet form, TFS can be supplied in different specifications to meet diverse production needs.
Product Application

FAQ
Can Tin Free Steel be used for can bodies?
No, TFS is not typically used for can bodies due to its lower corrosion resistance compared to tinplate. It is mainly used for lids, ends, and coated components.
What is the main difference between TFS and tinplate?
TFS uses chromium coating and provides better coating adhesion, while tinplate uses tin coating and offers better corrosion resistance for can bodies.
Can specifications be customized?
Yes, thickness, width, temper, and surface finish can be customized according to your application.
When should I choose TFS instead of tinplate?
TFS is a good choice for parts that require strong coating adhesion and painting, such as can ends, lids, and closures. It is often used where cost efficiency and coating performance are important.
Is TFS suitable for food contact applications?
TFS is usually used with coating systems. When combined with proper coatings, it can meet food packaging requirements for specific components such as can ends.
