Description

TMBP Coils (Tin Mill Black Plate) represent a highly specialized category of light-gauge, surface-critical cold-rolled steel. Manufactured through intense cold-reduction processes followed by precise annealing and temper rolling, TMBP is engineered to provide tight dimensional tolerances and exceptional flatness that standard cold-rolled sheets cannot match.

While famously utilized as the foundational raw material to produce Electrolytic Tinplate (ETP) and Tin-Free Steel (TFS/ECCS), TMBP is increasingly favored on its own for applications requiring extreme malleability without the initial cost of a metallic coating. Sourced by Metal Mart from leading global mills, our TMBP coils feature a protective electrostatic oil film on both sides to prevent environmental oxidation during transit, ensuring the material arrives at your facility ready for immediate stamping, lacquering, or processing.

Key Features:

• Ultra-Light Gauge Precision: Available in exceptionally thin ranges (down to 0.14 mm) with highly uniform cross-sections to maximize production yields per metric ton.

• Exceptional Deep-Drawing Ability: Optimized metallurgy allows the steel to undergo severe stretching, forming, and shaping into multi-piece containers without splitting.

• Controlled Surface Finishes: Available in bright, stone, or matte surface textures, providing an optimal surface anchor for the adhesion of organic lacquers, polymers, or specialized inks.

• Flexible Temper Options: Available in both Single-Reduced (SR) for standard workability and Double-Reduced (DR) tempers for maximum stiffness and structural economy.

Technical Specifications:

• Material Designation: Tin Mill Black Plate (TMBP)

• Standard: JIS G3303 / ASTM A623 / DIN EN 10203

• Thickness Range: 0.14 mm to 0.60 mm

• Steel Substrate Types: Type MR (general purpose), Type L (high corrosion resistance), and Type D (aluminum-killed for severe drawing).

• Quality Documentation: Accompanied by rigorous Mill Test Certificates (MTC) documenting exact Rockwell hardness (30-T scale) and chemical compositions.

Common Applications:

• Packaging Components: Stamped lids, can ends, easy-open tabs, crowns, screw caps, and aerosol components.

• Industrial & Household Goods: Dry battery jackets, lipstick shells, jewelry boxes, lighting fixtures, and metal spools.

• Automotive Internals: Precision-stamped oil filter casings, brackets, and deep-drawn internal shells.

• Construction Infrastructure: Base material for light-gauge cable armor, ceiling suspensions, and expanded metal laths.
