Comparison of Tinplate and TFS

Comparison of Tinplate and TFS

Bare corrosion resistance is evaluated under tightly sealed conditions. Evaluation of each product may change according to the contents actually packed. Please consult supplier in advance.
Corrosion resistance after painting is evaluated by crosshatching corrosion tests. Evaluation of each product may change according to actual use conditions.
The evaluation is for the case where welding is performed without grinding the surface to remove the metallic coating layer.

High-temperature baking after painting and printing may cause changes in material properties.
