Tin Mill Black Plate (TMBP/BP)

Price:  

Tin Mill Black Plate (TMBP/BP)
Tinplate Production: TMBP is primarily used as a base material for producing tinplate, which is extensively used in making food and beverage cans, aerosol containers, and other packaging applications.
Tin-Free Steel: It serves as the substrate for tin-free steel (electrolytic chromium coated steel), which is used in similar packaging applications as tinplate but offers different surface and corrosion-resistant properties.
Crown Caps: TMBP is used in the manufacturing of crown caps for bottles, ensuring a secure seal for beverages.
Automotive Parts: Due to its excellent mechanical properties, TMBP is also used in the production of certain automotive components.
Household Appliances: Used in the manufacturing of various parts for household appliances that require a thin, strong, and formable material.

Tin Mill Black Plate (TMBP/BP) is an uncoated, thin, and cold-rolled steel sheet that serves as a substrate for tinplate and tin-free steel production. It is made from low-carbon steel and is characterized by its smooth surface finish, uniform thickness, and good mechanical properties. TMBP is processed through several stages, including cold rolling and annealing, to achieve the desired specifications. This material is essential in the production of various coated steels used in packaging and other industries.
